a Temperature distribution as a function of depth and time on TRAPPIST 1 g for a 1 km thick ice sheet, Ts of 200 K, and heat flow of 175 mW m−2. b Ice phase evolution as a function of depth and time on TRAPPIST 1 g over a 5-million-year time frame. c Temperature distribution as a function of depth and time on Kepler 442 b for a 4 km thick ice sheet, Ts of 260 K, and heat flow of 10 mW m−2. d Ice phase evolution as a function of depth and time on Kepler 442 b over a 5-million-year time frame.
