Table 1.

Duration of the group 1 BSG ^(a) phase and of the group 2 BSG ^(a) phase for different models computed with the Ledoux criterion for convection.

Mass	Rotation	Comment	BSG1 duration	BSG2 duration
M_⊙	V/V_crit, ini		kyr	kyr
20	0.4	Increased Ṁ_RSG	11.5	500.3
25	0.0	–	8.3	306.0
25	0.4	–	6.6	375.1
20	0.4	Overshoot 0.3 H_P	6.0	442.4

Notes. These models have a solar metallicity (Z_⊙ = 0.014).

^(a)

Here we consider the model as a BSG if it has left the MS and if 3.9 < log(T_eff)< 4.4.
