Collapse or Explosion of C+O White Dwarfs
The existence and the orbital parameters of low-mass binary x-ray sources suggest that a fraction at least of neutron stars have been produced by the accretion induced collapse (AIC) of a white dwarf (TAAM and VAN DEN HEUVEL ). Two types of candidates have been proposed thus far: carbon-oxygen white dwarfs (CANAL and SCHATZMANN ; CANAL and ISERN ; CANAL, ISERN and LABAY ), and oxygen-neon-magnesium white dwarfs (MIYAJI et al ; MIYAJI and NOMOTO ).
