Searching for Supernova Survivors
Supernovae may be among the most powerful events in the cosmos, but astronomers think that companion stars may be able to survive these intense explosions.
Judging a book by its cover: estimating red supergiant masses from their surface abundance
Can astronomers use core-collapse supernova to find out the mass of their progenitors? Find out in today’s bite!
Blank Sky But Not Blank Information
Archival data are able to place constraints on the origin of supernova 2011fe.
Progenitors of AM CVn systems
The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
Evidence for two distinct populations of Type Ia Supernovae
Type Ia Supernovae are extensively used in astronomy research, but the progenitors of these massive explosions are still not well understood. This paper discusses new evidence that there are two distinct populations of type Ia supernovae, and that they originate from different stellar populations.
Exploding diamonds in the sky
Pakmor et al. propose a new mechanism to make Type 1a supernova explosions from a pair of white dwarfs.
