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 ...

Neutrino-driven Winds in Three-dimensional Core-collapse Supernova Simulations [PDF]
The Astrophysical Journal, 2023 In this paper, we analyze the neutrino-driven winds that emerge in 12 unprecedentedly long-duration 3D core-collapse supernova simulations done using the code F ornax .

Gravitational waves and core-collapse supernovae [PDF]
, 2017 A mechanism of formation of gravitational waves in the Universe is considered for a nonspherical collapse of matter. Nonspherical collapse results are presented for a uniform spheroid of dust and a finite-entropy spheroid. Numerical simulation results on

Critical Condition of Core-collapse Supernovae. I. One-dimensional Models [PDF]
The Astrophysical JournalWhen the core of a massive star collapses, neutrino heating can energize the stalled accretion shock, leading to a successful supernova. The critical condition that characterizes the transition from accretion to explosion is a central topic of study and ...

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.

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 ...

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.

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.

Revealing the Progenitor of SN 2021zby through Analysis of the TESS Shock-cooling Light Curve
The Astrophysical Journal Letters, 2023 We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) SN 2021zby. TESS captured the prominent early shock-cooling peak of SN 2021zby within the first ∼10 days after explosion with a 30 minute cadence.
