Theory of core-collapse supernovae [PDF]
Physics Reports, 2007 Advances in our understanding and the modeling of stellar core-collapse and supernova explosions over the past 15 years are reviewed, concentrating on the evolution of hydrodynamical simulations, the description of weak interactions and nuclear equation of state effects, and new insights into the nucleosynthesis occurring in the early phases of the ...

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 ...

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.

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 ...

The Type II-P Supernova 2019mhm and Constraints on its Progenitor System
The Astrophysical Journal, 2023 We present pre- and postexplosion observations of the Type II-P supernova (SN II-P) 2019mhm located in NGC 6753. Based on optical spectroscopy and photometry, we show that SN 2019mhm exhibits broad lines of hydrogen with a velocity of −8500 ± 200 km s ...

Black Hole Formation Accompanied by the Supernova Explosion of a 40 M ⊙ Progenitor Star
The Astrophysical Journal, 2023 We have simulated the collapse and evolution of the core of a solar-metallicity 40 M _⊙ star and find that it explodes vigorously by the neutrino mechanism, despite its very high “compactness.” Within ∼1.5 s of explosion, a black hole forms.

Core-collapse Supernovae [PDF]
Proceedings of VI European Summer School on Experimental Nuclear Astrophysics — PoS(ENAS 6), 2013 Marking the inevitable death of a massive star, and the birth of a neutron star or black hole, core-collapse supernovae bring together physics at a wide range in spatial scales, from kilometer-sized hydrodynamic motions (growing to gigameter scale) down to femtometer scale nuclear reactions. Carrying 10$$^{51}$$ ergs of kinetic energy and a rich-mix of

Turbulence in core-collapse supernovae [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 Multidimensional simulations show that non-radial, turbulent, fluid motion is a fundamental component of the core-collapse supernova (CCSN) explosion mechanism. Neutrino-driven convection, the standing accretion shock instability, and relic-perturbations from advanced stages of nuclear burning can all impact the outcome of core collapse in a ...
