Evolution of the planet masses as a function of the age. The initial mass of the planets is 0.02 M_Jup, being the smallest in the mass range considered in our study. The stellar model is for a 1 M_⊙ star beginning its evolution with a surface velocity of 40 km s⁻¹, 30 Myr before the ZAMS. Each curve is labeled by the orbital period of the planet at the end of the evolution (see text) in units of Earth days. From the shortest to the longest orbital period, the initial distance has the following respective values in au: 0.0100, 0.0150, 0.0250, 0.0450, 0.0650, 0.0850, 0.1100, 0.1294.
