Evolutionary tracks from the Steam Worlds Evolution (SWE) model (Aguichine et al. 2025, in prep). Model summary:Earth-like core (32.5% iron-sulfur alloy, 67.5% mantle with Earth-like Fe/Si ratio)Pure H2O envelope and pure H2O atmosphere connected at P_b = 1000 barParameters:ST: Stellar Type (M or G), for radiative transfer in the atmosphereWMF: Water Mass Fraction, between 0.001 and 1T_eq: Equilibrium temperature (K), between 500 K and 700 KM_p: Planet mass (M_e), between 0.2 M_E and 20.0 M_EAge: Host star age (Gyr), between 0.01 Gyr and 20 Gyr, assuming the planet formed at t_0 = 10 Myr (can be adjusted)Model outputs:R_p: Planet radius (R_E) at 20 mbarR_b: Planet radius (R_E) at 1000 barT_b: Temperature (K) at 1000 bar)T_int: Intrinsic temperature (K), nominal values are between 10 K and 400 Ks_env: Specific entropy of H2O in the envelope (in J/K/kg)Sources of energy for the cooling, expressed as luminosities (in W):L_env: energy from the H2O envelope (thermal + gravitational)L_rad: radiogenic heat produced in the coreL_core: thermal energy of the coreL_grav: gravitational energy of the coreBy construction:L_env + L_rad + L_core + L_grav = (4 * Pi * R_p**2) * (sigma_SB * T_int**4)NB: The last line of each track represents an estimate of the time until "full exhaustion" (see paper for details).
