We present equation of state data of shock compressed hydrogen and deuterium.
These have been calculated in the physical picture by using {\it ab initio}
molecular dynamics simulations based on finite temperature density functional
theory as well as in the chemical picture via the Saha-D model. The results are
compared in detail with data of shock wave experiments obtained for condensed
and gaseous precompressed hydrogen and deuterium targets in a wide range of
shock compressions from low pressures up to megabars.

    • ". By scaling the initial density, theoretical hydrogen EOSs can reasonably be compared to deuterium experimental data, although some differences between D and H become non-negligible in the molecular region, which are probed by the gas gun data, due to differences in the molecular vibrational states; see Holst et al. (2012) for a detailed discussion. Figure 1 also shows the theoretical hydrogen Hugoniot curves for H- REOS.2 (Holst et al., 2012, with additional data points by A. Becker pers. comm), for the H-SCvH-i EOS, and for the H-Sesame EOS. "

    ABSTRACT: The core mass of Saturn is commonly assumed to be 10-25 ME as predicted by interior models with various equations of state (EOSs) and the Voyager gravity data, and hence larger than that of Jupiter (0-10 ME). We here re-analyze Saturn's internal structure and evolution by using more recent gravity data from the Cassini mission and different physical equations of state: the ab initio LM-REOS which is rather soft in Saturn's outer regions but stiff at high pressures, the standard Sesame-EOS which shows the opposite behavior, and the commonly used SCvH-i EOS. For all three EOS we find similar core mass ranges, i.e. of 0-20 ME for SCvH-i and Sesame EOS and of 0-17 ME for LM-REOS. Assuming an atmospheric helium mass abundance of 18%, we find maximum atmospheric metallicities, Zatm of 7x solar for SCvH-i and Sesame-based models and a total mass of heavy elements, MZ of 25-30 ME. Some models are Jupiter-like. With LM-REOS, we find MZ=16-20 ME, less than for Jupiter, and Zatm less than 3x solar. For Saturn, we compute moment of inertia values lambda=0.2355(5). Furthermore, we confirm that homogeneous evolution leads to cooling times of only about 2.5 Gyr, independent on the applied EOS. Our results demonstrate the need for accurately measured atmospheric helium and oxygen abundances, and of the moment of inertia for a better understanding of Saturn's structure and evolution.

    ABSTRACT: The thermodynamic parameters—pressure and density—of quasi-isentropically compressed helium have been measured in a pressure range of 100–500 GPa. A thermodynamic model that satisfactorily describes the behavior of strongly compressed helium in a wide range of compression parameters has been proposed.

    ABSTRACT: Model SAHA-S based on chemical picture for equation of state of solar plasma is presented. Effects of Coulomb interaction, exchange and diffraction effects, free electron degeneracy, relativistic corrections, radiation pressure contributions are taken into account. Solar model based on SAHA-S taking into account extended element composition and variation of heavy element abundance is represented and discussed. Comparison of SAHA-S equation of state data for hydrogen plasma with the results of other models applicable to description of solar plasma equation of state and results obtained with first principle methods is demonstrated and discussed.
