Abstract

The bulk properties of exoplanets: mass, radius and stellar irradiation, are the astronomers' view into planet interiors outside our solar system. I will give an update on the mass-radius diagram of known planets as of 2025, while addressing the underlying limitations and biases of our methods

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. Reference: EOS Manual.. Li Zeng, Stein B. Jacobsen, Dimitar D. Sasselov, and Michail I. Petaev. November 2022
