Progenitors of Core-Collapse Supernovae [PDF]

Annual Review of Astronomy and Astrophysics, 2009
Knowledge of the progenitors of core-collapse supernovae is a fundamental component in understanding the explosions. The recent progress in finding such stars is reviewed. The minimum initial mass that can produce a supernova (SN) has converged to 8 ± 1 M⊙from direct detections of red supergiant progenitors of II-P SNe and the most massive white dwarf ...

On the progenitors of core-collapse supernovae [PDF]

Astrophysics and Space Science, 2010
Theory holds that a star born with an initial mass between about 8 and 140 times the mass of the Sun will end its life through the catastrophic gravitational collapse of its iron core to a neutron star or black hole. This core collapse process is thought to usually be accompanied by the ejection of the star's envelope as a supernova.

Anisotropies in Core Collapse Supernovae

Chinese Journal of Astronomy and Astrophysics, 2006
Core-collapse supernovae are the final stage of the evolution of massive stars. When these have previously lost their hydrogen and helium envelopes, the supernova explosion is classified as Type Ic. This class of supernovae are particularly interesting because of the link with long-duration Gamma-Ray Bursts.

Core collapse supernovae

AIP Conference Proceedings, 2007
In this contribution I highlight some of the new findings concerning core‐collapse, type II supernovae. In particular, after some comments on SN statistics, I review the case for a large spread in ejecta and Ni mass, the discovery of a population of faint, low energy events and the increasing evidences of the presence of dense circumstellar material ...
