  • Stars more massive than about 8 Mend their lives as a supernova (SN), an event of fundamental importance Universe-wide. Theoretically, these stars have been expected to be either at the red supergiant, blue supergiant, or Wolf-Rayet stage before the explosion. We performed coupled stellar evolution and atmospheric modeling of stars with initial masses between 20 Mand 120 M� . We found that the 20 Mand 25 Mrotating models, before exploding as SN, have spectra that do not resemble any of the… CONTINUE READING
