Formation of binary millisecond pulsars by accretion-induced collapse of white dwarfs

Hurley, Jarrod; Tout, Christopher A; Wickramasinghe, Dayal; Ferrario, Lilia; Kiel, Paul D


It has generally been assumed that neutron stars (NSs) that become millisecond pulsars (MSPs) originated in a core-collapse supernova. The possibility of formation by accretion-induced collapse (AIC) of an oxygen/neon white dwarf (WD) has largely been ignored or considered negligible. Here, we demonstrate that population synthesis calculations with generic assumptions yield birthrates of binary MSPs via AIC that are comparable to and can exceed those for core collapse. Allowing both modes for...[Show more]
