Evolution of P_rot, ⋆(t) as a function of P_orb(t) and stellar mass for a 2 M_jup (upper panel) and 5 M_jup (lower panel) planet. The color gradient corresponds to the relative rotational departure δP_rot = 1 − P_rot, isol./P_rot, ⋆. Only systems where the planet is still present are plotted. The blue lines (composed of plain circles) depict the evolution of a given star-planet system (P_rot, init = 10.8 days and SMA_init = 30%R_co) in the P_rot, ⋆(t) − P_orb(t) plane. The red area shows the domain of applicability of gyrochronology analysis.
