Probability of destructing the satellite and producing a retrograde obliquity as a function of the mass of the satellite (bottom axis), its initial semi-major axis (vertical axis), and its migration timescale (labels). Each pixel features 96 numerical integrations over 4 Gyr with random initial angles (same setting as in Fig. 10). In the upper panels, the satellite is removed when it collides into the planet (q < R_eq). In the lower panels, the satellite is removed when it goes below the Roche limit (q < 2 R_eq). White pixels mean that the satellite survived in all 96 simulations. Coloured pixels show the fraction of simulations in which the satellite is destructed and the planet’s spin axis ends in the retrograde family. Resonances are labelled in panel a.
