Temperature (left) and pressure (right) profiles in the envelope of a planet with M = 0.1 M_⊕ (purple curves) and M = 0.68 M_⊕ (orange curves). The distance to the surface of each planet is given in units of the Hill radius of the planets. The solid circle shows the position of the respective Bondi radius. The temperature and pressure in the envelope increase with the mass of the planet. Since the planet is migrating inward as it grows, the pressure in the surrounding disk increases while the Hill radius shrinks. The planet with M = 0.68 M_⊕ develops a radiative region in the inner envelope indicated by the dotted line style.
