Notes. “Stage” column denotes if star is moving to the red in the HR diagram (first stage) or moving to the blue (second stage). “fBSG” indicates the time spent between log(Teff) = 3.9 and 4.4 for a given stage as a fraction of the total BSG lifetime of each model. τBSG indicates the lifetime of the BSG stage in kyr. Not all of these evolutionary points are considered BSGs (see X surface fractions). The rows in italics correspond to models that return to the blue due to mass loss, at a temperature log(Teff) > 3.9 and therefore technically produce only one BSG stage. We include the parameters of these models when it has log(Teff) = 4.1 in the stage 2 rows.
