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, Gamma Velorum,[2] Mu Cephei, and members of the Quintuplet Cluster.
[3] 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.
