a) Expected tidal deformation of USPs parametrized as a (R₁ − R₃)/R₁ as a function of P_orb/P_Roche. Here the planets are approximated as compressed ellipsoids with primary axes radii of R₁, R₂, and R₃, where R₁ is the radius of the planet pointing toward the star, and R₃ is the radius along the orbit normal. We see that TOI-2431 b is among some of the most tidally distorted USP planets. b) Roche limit timescales of USPs as a function of P_orb/P_Roche. The latter indicates the proximity to the Roche limit, and the former indicates the timescale to reaching the Roche limit. We see that TOI-2431 b has the shortest timescale until tidal disruption of ~31 Myr.
