Question Regarding BPASS models #41

Closed RyotaInagaki1 closed 4 years ago

RyotaInagaki1 commented 4 years ago

Do the BPASS binary stellar population models used for Hoki include single stars? This is since in the BPASS v2.2 release paper it is stated that "In BPASS v2.2 we implement a new set of weighting parameters for binary fraction, period and mass ratio dis- tribution, as a function of the mass of the primary star. We base our new binary parameter distribution on those deter- mined by the detailed study of Moe & Di Stefano (2017, hereafter MS17) . . ." (Stanway et. al 2018).

The binary models include a realistic fraction of binary stars so yes there will be single stars in that population! You can check if a model is single or not by checking the "type": -1 is single :D
