Title: Demonstration of an x-ray Raman spectroscopy setup to study
    warm dense carbon at the high energy density instrument of European
    XFEL

  We present a proof-of-principle study demonstrating x-ray Raman
  Spectroscopy (XRS) from carbon samples at ambient conditions in
  conjunction with other common diagnostics to study warm dense
  matter, performed at the high energy density scientific instrument
  of the European x-ray Free Electron Laser (European XFEL). We obtain
  sufficient spectral resolution to identify the local structure and
  chemical bonding of diamond and graphite samples, using highly annealed
  pyrolytic graphite spectrometers. Due to the high crystal reflectivity
  and XFEL brightness, we obtain signal strengths that will enable
  accurate XRS measurements in upcoming pump-probe experiments with a
  high repetition-rate, where the samples will be pumped with high-power
  lasers. Molecular dynamics simulations based on density functional
  theory together with XRS simulations demonstrate the potential of this
  technique and show predictions for high-energy-density conditions. Our
  setup allows simultaneous implementation of several different diagnostic
  methods to reduce ambiguities in the analysis of the experimental
  results, which, for warm dense matter, often relies on simplifying
  model assumptions. The promising capabilities demonstrated here provide
  unprecedented insights into chemical and structural dynamics in warm
  dense matter states of light elements, including conditions similar
  to the interiors of planets, low-mass stars, and other celestial bodies.

Title: Measuring the structure and equation of state of polyethylene
    terephthalate at megabar pressures

  We present structure and equation of state (EOS) measurements
  of biaxially orientated polyethylene terephthalate (PET,
  (<SUB>C1<SUB>0</SUB>H<SUB>8</SUB>O<SUB>4</SUB>) n</SUB>?, also called
  mylar) shock-compressed to (155 ±20 ?) GPa and (6000 ±1000 ?) K
  using in situ X-ray diffraction, Doppler velocimetry, and optical
  pyrometry. Comparing to density functional theory molecular dynamics
  (DFT-MD) simulations, we find a highly correlated liquid at conditions
  differing from predictions by some equations of state tables,
  which underlines the influence of complex chemical interactions
  in this regime. EOS calculations from ab initio DFT-MD simulations
  and shock Hugoniot measurements of density, pressure and temperature
  confirm the discrepancy to these tables and present an experimentally
  benchmarked correction to the description of PET as an exemplary
  material to represent the mixture of light elements at planetary
  interior conditions.

  Until recently, iron oxides were assumed to comprise only FeO, Fe3O4,
  and Fe2O3. However, static compression experiments have demonstrated
  the existence of new iron oxide stoichiometries at high pressure and
  temperature such as FeO2 [1], Fe4O5 [2], Fe5O6 [3], Fe13O19 [4]. These
  discoveries, with the wide variety of iron oxides phases existing
  at high pressure [5], highlight the complexity of iron-oxygen phase
  diagram at extreme condition. In this context, measurements of physical
  properties, phase transition processes and phase diagrams of Fe-O
  systems with laser shock compression techniques offer opportunities to
  extend the actual pressure and temperature ranges of such studies. Here,
  we will present main results from a laser shock experiment at the ID24
  ESRF beamline using time-resolved X-ray absorption measurement on Fe2O3
  samples. In addition, we will show results from a recent experiment
  performed at LULI 2000 to measure the equation of state and calculate
  sound velocities along the Fe2O3 Hugoniot and above 500GPa. <P />[1]

Title: Chemistry and structural properties of C-H-O mixtures at
    conditions comparable to the interiors of ice giants

  The interiors of the ice giants Uranus and Neptune are dominated by
  a warm dense mixture of light elements, which presumably results in
  complex chemistry and phase transitions. New experimental capabilities,
  such as the combination of high-energy lasers and X-ray free
  electron lasers, allow for investigating such states of matter with
  unprecedented detail in the laboratory [1-6]. Here we show results
  from C-H-O samples dynamically compressed to pressures around 200
  GPa and heated to temperatures of few thousand kelvins. Structural
  changes recorded by both in situ X-ray diffraction and small angle
  X-ray scattering show phase separation of carbon, which is evidently
  not retarded or prevented by the presence of oxygen. In contrast, we
  find that carbon is transferred to diamond more effectively in C-H-O
  in comparison to C-H samples brought to similar conditions. These
  findings are in line with quantum simulations predicting that the
  presence of oxygen more supports than prevents the phase separation
  of carbon and hydrogen. Besides carbon precipitation, this process may
  also trigger the creation of isolated metallic hydrogen or superionic
  ices and therefore can have significant consequences for the internal
  structure of icy giant planets.

Title: Direct Observation of Shock-Induced Disordering of Enstatite
    Below the Melting Temperature

  We report in situ structural measurements of shock-compressed
  single crystal orthoenstatite up to 337 ± 55 GPa on the Hugoniot,
  obtained by coupling ultrafast X-ray diffraction to laser-driven shock
  compression. Shock compression induces a disordering of the crystalline
  structure evidenced by the appearance of a diffuse X-ray diffraction
  signal at nanosecond timescales at 80 ± 13 GPa on the Hugoniot, well
  below the equilibrium melting pressure (&gt;170 GPa). The formation
  of bridgmanite and post-perovskite have been indirectly reported in
  microsecond-scale plate-impact experiments. Therefore, we interpret
  the high-pressure disordered state we observed at nanosecond scale as
  an intermediate structure from which bridgmanite and post-perovskite
  crystallize at longer timescales. This evidence of a disordered
  structure of MgSiO<SUB>3</SUB> on the Hugoniot indicates that the
  degree of polymerization of silicates is a key parameter to constrain
  the actual thermodynamics of shocks in natural environments.

Title: Demonstration of X-ray Thomson scattering as diagnostics for

  The gas and ice giants in our solar system can be seen as a
  natural laboratory for the physics of highly compressed matter at
  temperatures up to thousands of kelvins. In turn, our understanding
  of their structure and evolution depends critically on our ability to
  model such matter. One key aspect is the miscibility of the elements
  in their interiors. Here, we demonstrate the feasibility of X-ray
  Thomson scattering to quantify the degree of species separation in a
  1:1 carbon-hydrogen mixture at a pressure of ~150 GPa and a temperature
  of ~5000 K. Our measurements provide absolute values of the structure
  factor that encodes the microscopic arrangement of the particles. From
  these data, we find a lower limit of 2 4<SUB>-7</SUB><SUP>+6</SUP>?% of
  the carbon atoms forming isolated carbon clusters. In principle, this
  procedure can be employed for investigating the miscibility behaviour
  of any binary mixture at the high-pressure environment of planetary
  interiors, in particular, for non-crystalline samples where it is
  difficult to obtain conclusive results from X-ray diffraction. Moreover,
  this method will enable unprecedented measurements of mixing/demixing
  kinetics in dense plasma environments, e.g., induced by chemistry or
  hydrodynamic instabilities.

Title: Measurement of diamond nucleation rates from hydrocarbons at

  We present measurements of the nucleation rate into a diamond lattice
  in dynamically compressed polystyrene obtained in a pump-probe
  experiment using a high-energy laser system and in situ femtosecond
  x-ray diffraction. Different temperature-pressure conditions that
  occur in planetary interiors were probed. For a single shock reaching
  70 GPa and 3000 K no diamond formation was observed, while with a
  double shock driving polystyrene to pressures around 150 GPa and
  temperatures around 5000 K nucleation rates between 10<SUP>29</SUP>
  and 10<SUP>34</SUP>m<SUP>-3</SUP> s<SUP>-1</SUP> were recorded. These
  nucleation rates do not agree with predictions of the state-of-the-art
  theoretical models for carbon-hydrogen mixtures by many orders of
  magnitude. Our data suggest that there is significant diamond formation
  to be expected inside icy giant planets like Neptune and Uranus.

  The effects of hydrocarbon reactions and diamond precipitation on
  the internal structure and evolution of icy giant planets such
  as Neptune and Uranus have been discussed for more than three
  decades<SUP>1</SUP>. Inside these celestial bodies, simple
  hydrocarbons such as methane, which are highly abundant in
  the atmospheres<SUP>2</SUP>, are believed to undergo structural
  transitions<SUP>3,4</SUP> that release hydrogen from deeper layers
  and may lead to compact stratified cores<SUP>5-7</SUP>. Indeed,
  from the surface towards the core, the isentropes of Uranus and
  Neptune intersect a temperature-pressure regime in which methane
  first transforms into a mixture of hydrocarbon polymers<SUP>8</SUP>,
  whereas, in deeper layers, a phase separation into diamond and
  hydrogen may be possible. Here we show experimental evidence for
  this phase separation process obtained by in situ X-ray diffraction
  from polystyrene (C<SUB>8</SUB>H<SUB>8</SUB>)<SUB>n</SUB> samples
  dynamically compressed to conditions around 150 GPa and 5,000 K;
  these conditions resemble the environment around 10,000 km below the
  surfaces of Neptune and Uranus<SUP>9</SUP>. Our findings demonstrate
  the necessity of high pressures for initiating carbon-hydrogen
  separation<SUP>3</SUP> and imply that diamond precipitation may require
  pressures about ten times as high as previously indicated by static
  compression experiments<SUP>4,8,10</SUP>. Our results will inform
  mass-radius relationships of carbon-bearing exoplanets<SUP>11</SUP>,
  provide constraints for their internal layer structure and improve
  evolutionary models of Uranus and Neptune, in which carbon-hydrogen
  separation could influence the convective heat transport<SUP>7</SUP>.

Title: The Deflection of Light during a Solar Eclipse
Authors: Schuster, Arthur
Bibcode: 1920Natur.104..468S
Altcode:
  IN discussing the effects of atmospheric refraction during solar
  eclipses Prof. Anderson disregards the shallowness of the effective
  layer of air as compared with the diameter of the moon's shadow. Unless
  the sun be very near the horizon, a line of sight drawn from the centre
  of the umbra to a point in the corona will remain within the umbra right
  through this layer. This consideration vitiates the method of solution
  adopted by Prof. Anderson, and consequently its results. On reading his
  first letter (NATURE, December 4, 1919) I was struck by the ingenuity
  of his explanation, more especially as I believe he under valued the
  amount of the angular deviation arrived at on his theory through taking
  the sun's radius to be half, instead of a quarter of, a degree. In
  view of the importance of the subject, a fuller investigation seemed
  to be required. I hope soon to publish a note giving the complete
  solution of the problem, and may therefore confine myself here to
  a statement of the result, which is quite fatal to Prof. Anderson's
  explanation. I take the altitude of the sun to be 45° and the maximum
  fall of temperature 4° the figures given may easily be modified to suit
  other conditions. I further assume the most favourable distribution
  of temperature, which is that adopted by Prof. Anderson, when the
  line of maximum fall of temperature is parallel to the edges of the
  moon's shadow and independent of altitude. Two stars at a distance of
  three solar, diameters from each other might then show an increase in
  apparent distance owing to refraction amounting to the 240,000th part
  of a second of arc. If the diminution of the temperature effect with
  altitude be taken into account, this figure should be divided by 4.

Title: The Green Flash
Authors: Schuster, Arthur
Bibcode: 1915Natur..95....8S
Altcode:
  PROF. PORTER'S explanation of the green flash (NATURE, February 18)
  is unable to account for its appearance at sunrise, when it can be
  observed with great brilliance. When I was passing through the Indian
  Ocean on my way to observe the total eclipse of 1875 I happened to
  be on deck before sunrise one morning, and, watching for the first
  ray of the sun, was surprised to see the first flash of light appear
  as a vivid green. I had never heard of the phenomenon before, but
  atmospheric dispersion seemed to me sufficient to account for it, and
  I took it for granted that it was a well-known occurrence. I continued
  to observe the same effect several mornings in succession.

Title: On the Magnetic Action of Sun-spots.
Authors: Schuster, Arthur
Bibcode: 1909Natur..79..279S
Altcode:
  IT was perhaps to be expected that the recent discovery of the Zeeman
  effect in the spectra of sun-spots should revive the idea of a direct
  magnetic action originating in the sun and observable at the surface
  of the earth. A numerical estimate is therefore called for as to
  the magnitude of the disturbance which might be produced by such a
  direct action.

Title: The 4.79 Period of Sun-spot Activity
Authors: Schuster, Arthur
Bibcode: 1908Natur..79....7S
Altcode:
  IN NATURE of August 13 (p. 351) the photograph is published of two
  groups of sun-spots taken on August 6, and attention is directed to the
  remarkable fact that such an outbreak should occur two years after the
  sun-spot maximum. This renewed sun-spot activity is connected with the
  4.79 period, which I have shown to have been quite persistent-even more
  so than the eleven-year period-since sun-spots were first systematically
  observed. In a paper published in the Philosophical Transactions for
  1906 I gave the times of maxima of this period as being 1903.72+4.79
  n. This would bring the maximum to 1908.51, or to about July 1 of the
  present year. A retardation of one month in a period of more than four
  years' duration is, of course, insignificant.

Title: A Plea for Absolute Motion
Authors: Schuster, Arthur
Bibcode: 1906Natur..73..462S
Altcode:
  NEWTON believed in the possibility of absolute motion (i.e. motion in
  space not necessarily relative to other material bodies), founding his
  argument on the fact that the rotation of a planet might be detected
  by experiment on the planet itself without reference to outside
  bodies. Newton's reasoning is unanswerable, but it only takes us part
  of the way. Though it proves that using the principle of gyrostatic
  action we can determine direction in space absolutely, it fails
  to distinguish one parallel line from another. We can only observe
  relative motion. This statement, which no one doubts, is generally
  taken to be synonymous with the assertion that nothing but relative
  motion will ever be known. So firmly is this generalisation rooted in
  the present generation of philosophers that I am afraid the expression
  of a contrary opinion will only result in placing its author on the
  ``Index'' of De Morgan's Budget of Paradoxes.
