Type II supernovae from prompt explosions

Physical Review Letters, 1987
Evidence is cited that supernova 1987A involved a large explosion energy, of about (2-3) x 10 to the 51st ergs. Such large explosion energy has not come from delayed shocks to date, nor is it likely to. Improved physics in the presupernova evolution, especially the inclusion of Coulomb interactions, has brought the iron-core mass down by less than ...

Type II Supernovae

1984
Evidence is briefly reviewed for believing that the core bounce mechanism actually gives rise to Type II supernovae in massive stars. Strongest evidence comes from the historical observation of the Crab Nebula light curve, the existence of pulsars, and from the nucleosynthesis of a few very neutron-rich isotopes such as 48Ca.

Underluminous type II-P supernovae

AIP Conference Proceedings, 2009
We present photometric and spectroscopic data for the largest sample of underluminous type IIP supernovae ever studied. We compare their light curves and spectra with those of normal SNe IIP in order to delineate the characteristics of this family of core‐collapse events.

Models of Type II Supernovae and Supernova 1987A

1989
Implications from the observations of SN 1987A for the standard model of type II supernova explosions are discussed. In particular, we find evidence for strong mixing prior to the explosion of SN 1987A, which was not expected from simple spherically symmetric models.
