Simulations of the progenitors of black hole--neutron star gravitational wave sources

Description

Recent discoveries of gravitational wave (GW) events most likely originating from black hole (BH) + neutron star (NS) mergers reveal the existence of BH+NS binaries. In this work, we perform the first complete 1D~model of three BH+NS progenitor systems which are calculated self-consistently until the iron core collapse.  We apply the \texttt{MESA} code starting from a post-common envelope binary consisting of a BH and a zero-age main-sequence helium star that experiences stable mass transfer until the infall velocity of the collapsing iron core exceeds 1000kms1
Our three simulated systems (A, B, and C) eventually evolve into BH+NS binaries with 
component masses of (MBH,MNS)=(8.80,1.53), (8.91,\,1.45), and (5.71,\,1.34)\;M, respectively. Here attached are the inlist-files. (zip=tar.xz)
