Core-collapse supernova explosion theory
Nature, 2020Most supernova explosions accompany the death of a massive star. These explosions give birth to neutron stars and black holes, and eject solar masses of heavy elements.

Is the Supernova 1950E a Supernova?
Publications of the Astronomical Society of Japan, 1990Abstract The supernova (SN) 1950E in the galaxy Zw 065.001 was found by Chai and van den Bergh (1970; AAA 04.125.005) on Palomar Observatory Sky Survey (POSS) plates. We have measured its position accurately and have found that the position on the blue print of POSS is different by about 3″ from that on the red print.

An extremely energetic supernova from a very massive star in a dense medium
Nature Astronomy, 2020The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to thermal energy.

SUPERNOVA EXPLOSIONS AND SUPERNOVA NEUTRINOS
Neutrinos in Physics and Astrophysics, 2000We summarize the current status of core-collapse supernova theory, in particular as it relates to multi-dimensional effects and neutrino transport . Highlighted are pulsar kicks , neutrino burst signatures, many-body effects, and observed asphericities that may have a bearing on the mechanism of supernova explosions .

Supernovae and Supernova Remnants
1983Supernovae are the result of explosions which terminate the life of massive stars. The amount of energy released by the supernovae in our galaxy is so large that these explosions provide the dominant energy for the heating of the hot (T ≳ 106 K) IS component and for the kinetic energy of the large scale motions of the interstellar clouds.

Supernovae and supernova remnants
2001A supernova explosion is among the most dramatic events that can be seen. The term ‘supernova’ is somewhat misleading, as such an event represents not a new star (that is, a ‘nova’), but instead the end of a star’s life. Nuclear fusion, the energy source of the stars, creates heavier elements from lighter elements.
