Purpose and Goals

The generation and diagnostics of extreme states of matter as appearing in the interior of planets, Brown Dwarfs and stars is one of the key scientific challenges at FLASH, the future European XFEL and the High Pressure Extreme Conditions beamline at PETRA III. This interdisciplinary research field combines problems and methods from planetary and astrophysics, and high-pressure and plasma physics. Therefore, a workshop series has been established by DESY, XFEL GmbH, DLR Berlin, Uni. of Rostock and Uni. of Bayreuth that brings together scientists from these fields to discuss related topics and problems. Earlier workshops were held at DESY Hamburg (2012) and DLR Berlin (2013).

The aim of the present workshop is to discuss scientific questions with relevance for extreme planetary environments in terms of high pressure (HP) and high temperature (HT).These conditions are prevalent in the deep interiors and atmospheric envelopes of solar system planets and satellites and massive solid and gas giant extrasolar planets, respectively, and are not fully accessible by conventional experimental and theoretical methods. New and enabling techniques to be used in the HP/HT regime are based on the combination of intense pulsed x-ray sources with pulsed sample excitation, in particular but not exclusively related to high energy optical lasers. Simultaneously, ab initio simulations for matter under extreme conditions provide a more and more predictive data set for planetary interiors in this HP/HT regime.

The preliminary program addresses the following topics

  • evolution and structure of giant planet interiors,
  • interior structure, bulk composition, and internal geodynamics of solid planets,
  • deep volatile cycles and exchange processes between geochemical reservoirs,
  • physics and chemistry of impact processes,
  • equations of state, petrology, and geochemistry of planetary materials,
  • melting relations and phase transformations of materials at extreme states,
  • dynamic and ultrafast processes in strongly excited solids or similar,
  • compression experiments using high-power optical and free electron lasers 
  • laboratory experiments using multi-anvil and diamond-anvil cells,
  • ab initio simulation studies for matter under extreme conditions.

Abstracts and contributions are welcome to the above subject areas that represent an initial outline and are open to further suggestions. The workshop will include a mix of solicited, contributed and poster presentations. This meeting is also intended to inspire new projects and offer scientific opportunities for future collaboration between workshop participants from distinct research fields.

The workshop will start on Sep, 24 at noon and will end on Sep, 26 at noon.
