Orbital evolution for 1 M_J planet with 0.02 ≤ a_in (AU) ≤ 0.1 and Ω_in = 3.2, 18 Ω_⊙ (top and bottom panels, respectively). The solid blue lines show the evolution of the orbital distance. The dotted red and dashed black lines indicate the evolution of a_min and a_cor, respectively. The Roche limit is shown by the black dotted line. The cyan and magenta shaded areas represent the extension of the stellar core and envelope along the evolution of the star, respectively.
