List of supernova candidates
This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages of their evolution. Prominent examples of stars in this mass range include Antares, Spica,[2] Gamma Velorum,[3] Mu Cephei, and members of the Quintuplet Cluster.[4] Type Ia supernova progenitors are white dwarf stars that are close to the Chandrasekhar limit of about 1.44 solar masses and are accreting matter from a binary companion star.
The list includes massive Wolf–Rayet stars, which may become Type Ib/Ic supernovae, particularly oxygen-sequence (Wolf-Rayet WO) stars. As of 2023, most of these candidates are in the Milky Way galaxy, however five oxygen-sequence Wolf-Rayet stars are also known in other galaxies.
