Variation of the maximum semi-major axis below which engulfment occurs during the RG ascent as a function of the mass of the planet, of the mass of the star, and its initial rotation rate. The dashed and continuous lines are, respectively, for an initial stellar angular velocity equal to 10% and 50% of the critical one. The empty symbols connected by light dashed-dotted lines are the results obtained by Villaver et al. (2014) for planets with masses of 1, 2, 5, and 10 M_J orbiting a non-rotating 1.5 M_⊙ star. The triangles are for models using weak mass loss rates during the red giant phase (η = 0.2 in Eq. (1)), the circles are for models with normal RG mass losses (η = 0.5), and the squares are for models with η = 0.5 and overshooting.
