Astronomy:Red supergiant problem
From HandWiki
The red supergiant problem in astrophysics, denotes the discrepancy between the upper mass limit of observed red supergiant progenitors to type II-P supernovae and the range of masses predicted by stellar evolution.[1] It was first described in 2009 by Stephen Smartt, who also coined the term.[1]
Discovery
After performing a volume-limited search for supernovae, Smartt et al. found the lower and upper mass limits for type II-P supernovae to form to be 8.5+1
−1.5 M☉ and 16.5±1.5 M☉ respectively. The former is consistent with the expected upper mass limits for white dwarf progenitors to form, but the latter is not consistent with massive star populations in the Local Group.[1]
