Approximations to the spin of close Black-hole–Wolf-Rayet binaries based on the simulations presented in Bavera et al. (2021).
Notice that the black-hole spin approximation presented in this work is model dependent on the core-collapse assumptions, which include Fryer et al. (2012) delayed core-collapse mechanism, fit to the (pulsational) pair-instability supernovae models of Marchant et al. (2019), up to 0.5 Msun neutrino mass and AM loss as implemented in Zevin et al. (2020), and the arbitrary minimum BH mass of 2.5 Msun. All assumptions about these simulations are explained in detail in Appendixes C and D of Bavera et al. (2021).
