The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
Pakmor et al. propose a new mechanism to make Type 1a supernova explosions from a pair of white dwarfs.
Starting in 2005 with SN 2005ap, astronomers began to detect new transients that are far more luminous than previously-known supernovae. With brightnesses ten times those seen in Type 1a’s, these new supernovae have been dubbed “ultraluminous supernovae.” This paper presents two new supernovae discovered by Pan-STARRS.
Supernovae are vitally important in the chemical and dynamical evolution of galaxies, but we don’t yet fully understand the physics that produce these explosions. This new work simulates the turbulent instabilities in a star at the brink of core-collapse.
