Physical mechanism of core-collapse supernovae that neutrinos drive [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesThe current understanding of the mechanism of core-collapse supernovae (CCSNe), one of the most energetic events in the universe associated with the death of massive stars and the main formation channel of compact objects such as neutron stars and black ...

Turbulence in Core-collapse Supernovae
The Astrophysical JournalIt is understood in a general sense that turbulent fluid motion below the shock front in a core-collapse supernova stiffens the effective equation of state of the fluid and aids in the revival of the explosion.

The mechanism(s) of core-collapse supernovae. [PDF]
Philos Trans A Math Phys Eng Sci, 2017 Core-collapse supernovae (CCSNe) are the explosions that attend the deaths of massive stars. Despite decades of research, several aspects of the mechanism that drives these explosions remain uncertain and the subjects of continued investigation. In this short review, I will give an overview of the CCSN mechanism and current research in the field.

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.

Magnetorotational Explosions of Core-Collapse Supernovae
Acta Polytechnica CTU Proceedings, 2014 Core-collapse supernovae are accompanied by formation of neutron stars. The gravitation energy is transformed into the energy of the explosion, observed as SN II, SN Ib,c type supernovae.

Effect of Protoneutron Star Magnetized Envelops in Neutrino Energy Spectra
Particles, 2022 The neutrino dynamics in hot and dense magnetized matter, which corresponds with protoneutron star envelopes in the core collapse supernova explosions, is considered.

Parameters of core collapse [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 This paper considers the phenomenon of deep core collapse in collisional stellar systems, with stars of equal mass. The collapse takes place on some multiple, $ξ^{-1}$, of the central relaxation time, and produces a density profile in which $ρ\propto r^{-α}$, where $α$ is a constant.

Early Hard X-Rays from the Nearby Core-collapse Supernova SN 2023ixf
The Astrophysical Journal Letters, 2023 We present NuSTAR observations of the nearby SN 2023ixf in M101 ( d = 6.9 Mpc) that provide the earliest hard X-ray detection of a nonrelativistic stellar explosion to date at δ t ≈ 4 days and δ t ≈ 11 days.

Neutrinos from core-collapse supernovae at KM3NeT [PDF]
EPJ Web of Conferences, 2023 The SN1987A supernova was the first extragalactic neutrino de- tection, but no further observations have been made since. Detecting neutrinos from a galactic supernova would provide invaluable information on the supernova mechanism and particle behavior ...
