Notes. fovershoot = 0.01, A2 = 0.12, and tacc = 5 Myr (see Table 1). The MXY, lost and MZ, planet values were calculated using the optimized Zproto value (see text for details). ΔZacc = Zacc,max − Zproto. See Fig. 4 for the definitions of M1 and M2. ( * )In MZ5, we assumed that there is no pebble accretion phase (i.e., M1 = M2), MXY, lost = 0, and MZ, planet = 150 M⊕; thus, M1 was determined by Zproto (see Eq. (9)).
