“Lossy” Roche-lobe overflow of a hot Jupiter with a 10 M_⊕ core as computed two different ways. Top to bottom, left panels: orbital period, photospheric radius R_p (R_R is the Roche radius), and bulk density. Top to bottom, right panels: mass, mass-loss rate, and entropy in the convective zone (innermost cell in MESA model). Light blue curves use the T. Hallatt & S. Millholland (2026a, 2026b) “following the adiabats” structure/thermal evolution model, while dark blue use MESA with hydrodynamics enabled. Regardless of planetary structure/thermal evolution details, lossy Roche-lobe overflow robustly destroys hot Jupiters (and produces desert dwellers).
