Returns
Mass ratio between donor and accretor in the previous step

◆ qcrit()

double Qcrit_Hurley_Webbink_Shao::qcrit ( Star *  donor,
Star *  accretor 
) const
overrideprotectedvirtual

Same qcrit from Hurley+02 with Webbink 1988 for giants, but with a special treatment accretion on a BH following the Shao+21 paper. In the Shao+21 paper (https://arxiv.org/pdf/2107.03565.pdf) there is a special treatment for the accretion on a BH. Therefore if the accretor is not a BH we use the classical qc from Hurley. In Shao+21 there is not really a constant value for qc, but there are a number of criteria that we have to take into account to estimate the stability of the mass transfer, then if the mass trasnfer is stable we use a very large value for qcrit otherwise a very small one.

Parameters
donorPointer to the donor star
accretorPointer to the accretor star
Returns
qcrit

Reimplemented from Qcrit_Hurley.

◆ qcrit_giant()

double Qcrit_Hurley_Webbink::qcrit_giant ( Star *  donor,
_UNUSED Star *  accretor 
) const
overrideprotectedvirtualinherited

Qcrit for giants (BSE phase 3,5,6) following qc = 0.362 + 1.0/(3.0*(1.0 - Mcore_fraction)) After Eq. 57 (not numbered) in Hurley+02 The equation comes from Webbink (1988) and it has been obtained from models for condensed polytropes.

Parameters
donor
accretor
Returns

Reimplemented from Qcrit_Hurley.
