Main thermodynamic parameters in the core for the hot end-member case depending on planet mass (different columns), planet iron content and iron number in mantle, assuming an Mg-Si-O ratio similar to Earth. First row: temperature in the centre of the planet, followed by the averaged core thermodynamic values for density, heat capacity, thermal expansion coefficient, and Grüneisen parameter. Each row uses a fixed colour scale to highlight the variation with planet mass.
