Magnetorotational Instability in Core-Collapse Supernovae [PDF]
Acta Physica Polonica B Proceedings Supplement, 2017 We discuss the relevance of the magnetorotational instability (MRI) in core-collapse supernovae (CCSNe). Our recent numerical studies show that in CCSNe, the MRI is terminated by parasitic instabilities of the Kelvin-Helmholtz type.

Progenitors of Core-Collapse Supernovae [PDF]
Proceedings of the International Astronomical Union, 2017 Massive stars have a strong impact on their surroundings, in particular when they produce a core-collapse supernova at the end of their evolution. In these proceedings, we review the general evolution of massive stars and their properties at collapse as ...

Fast neutrino flavor conversion in core-collapse supernovae: A parametric study in 1D models [PDF]
Physical Review D, 2023 We explore the impact of small-scale flavor conversions of neutrinos, the so-called fast flavor conversions (FFCs), on the dynamical evolution and neutrino emission of core-collapse supernovae (CCSNe).

Comprehensive constraints on heavy sterile neutrinos from core-collapse supernovae [PDF]
Physical Review D, 2023 Sterile neutrinos with masses up to O(100) MeV can be copiously produced in a supernova (SN) core through the mixing with active neutrinos. In this regard, the SN 1987A detection of neutrino events has been used to put constraints on active-sterile ...

Luminous Supernovae: Unveiling a Population between Superluminous and Normal Core-collapse Supernovae [PDF]
Astrophysical Journal, 2022 Stripped-envelope core-collapse supernovae can be divided into two broad classes: the common Type Ib/c supernovae (SNe Ib/c), powered by the radioactive decay of 56Ni, and the rare superluminous supernovae (SLSNe), most likely powered by the spin-down of

Explosive nucleosynthesis with fast neutrino-flavor conversion in core-collapse supernovae [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Fast neutrino (ν)-flavor conversion (FFC) is a possible game-changing ingredient in core-collapse supernova (CCSN) theory. In this paper, we examine the impact of FFC on explosive nucleosynthesis by including the effects of FFC in conjunction with ...

Prospects of Fast Flavor Neutrino Conversion in Rotating Core-collapse Supernovae [PDF]
Astrophysical Journal, 2021 There is mounting evidence that neutrinos undergo fast flavor conversion (FFC) in core-collapse supernova (CCSN). In this paper, we investigate the roles of stellar rotation on the occurrence of FFC by carrying out axisymmetric CCSN simulations with full

Statistical Properties of the Nebular Spectra of 103 Stripped-envelope Core-collapse Supernovae [PDF]
Astrophysical Journal, 2022 We present an analysis of the nebular spectra of 103 stripped-envelope (SE) supernovae (SNe) collected from the literature and observed with the Subaru Telescope from 2002 to 2012, focusing on [O i] λλ6300, 6363.

Core-collapse supernovae as cosmic ray sources. [PDF]
Mon Not R Astron Soc, 2018 Core-collapse supernovae produce fast shocks which expand into the dense circumstellar medium (CSM) of the stellar progenitor. Cosmic rays (CRs) accelerated at these shocks can induce the growth of electromagnetic fluctuations in the pre-shock medium.
