Temperature map of the inner planetary envelope during the growth process after the planet has reached a mass of M = 0.01 M. The distance to the surface of the planet is given in units of the instantaneous Hill radius of the planet. The gray lines show the sublimation locations of the representative minerals. The white dotted line represents the Bondi radius. The temperature in the envelope starts to increase once the planet reaches a mass of 0.01 M. For the final planet the temperature in the inner is ≈ 2700 K. The sublimation line of FeS moves out to r ≈ 0.03 RH. The sublimation lines of Mg2SiO4, and Fe lie close together. The sublimation temperature of A12O3 is only reached close to the surface of a planet with M > 0.4 M.
