EOS (Equation-Of-State) Manual For Exoplanets
Mass-radius curves of Hydrogen EOS of Mazevet 2019: the same color schemes of isentropes apply, but do not correspond to the temperature color scale on the upper-left. The temperature color scale is only for exoplanets plotted. or Becker 2014 Hydrogen EOS (Fig. 15), the constant central density contours are almost parallel to the constant bulk density contours (the gray dashed lines in the background marked by 0.3, 1, 3, 10 g/cc). This implies that the interior. — astro-ph.EP

The exoplanet field now abounds with new discoveries of planets and planetary systems. It is of great interest for the scientific community to understand the compositions and internal structures of these new planets outside our own solar system, and then infer their formation scenarios.

In particular, the proper implementation of the equation-of-states of various matters into the calculation of internal structure is crucial. Thus, we have come up with this write-up that provides the detailed steps to turn an equation-of-state (EOS) into a mass-radius relation of exoplanets, and highlight the physics and chemistry involved in these calculations. It must be visualized!
