Conditions of ocean formation for initially hot and steamy 1 R_⊕ planets synchronously rotating around an M3 star (T_★ ~ 3400 K). The figure depicts the evolution of surface temperature (top) and bond albedo (bottom) as a function of the incoming stellar flux, for four different bulk atmospheric compositions: 10 bar H₂O + 1 bar N₂ (M3), 3 bar H₂O + 1 bar N₂ (M3-3bar), 1 bar H₂O + 1 bar N₂ (M3-1bar), and 0.3 bar H₂O + 1 bar N₂ (M3-0.3bar).
