| contents | Knowledge of the formation of neutron stars (NSs) in supernova (SN) explosions is of fundamental importance in wide areas of contemporary astrophysics: X-ray binaries, magnetars, radio pulsars, and, not least, double NS systems which merge and become gravitational wave sources. A recent study by Richardson et al. reported that the NS in the Be-star/X-ray binary SGR 0755-2933 (CPD -29 2176) descended from an ultra-stripped SN. Using the same observational data as Richardson et al., however, we find that the majority of progenitor solutions for SGR 0755-2933 are of normal Type Ib/c SNe, which allows for up to several solar masses of material to be ejected in the SN event. To correctly probe the SN explosion physics and inferring pre-SN conditions in a binary system, a full kinematic analysis based on post-SN data is always needed. |
