Relativistic Jets in Core-collapse Supernovae [PDF]

open access: yesThe Astrophysical Journal Letters, 2019
Abstract After decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. One common mechanism is a neutrino-driven outflow, but others have been proposed. Among those, a long-standing idea is that jets play an important role in supernova (SN) explosions. Gamma-ray bursts (GRBs) that accompany “

The Iron Yield of Core-collapse Supernovae

open access: yesThe Astrophysical Journal, 2023
We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their ^56 Ni masses from the luminosity in their radioactive tails ( ${M}_{\mathrm{Ni}}^{\mathrm{tail}}$ ) and/or in their maximum light, and the mean ^56 ...

Progenitors of Core-Collapse Supernovae [PDF]

open access: yesAnnual 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 ...

Core-Collapse Supernova neutrino detection with KM3NeT [PDF]

open access: yesEPJ Web of Conferences, 2019
Core Collapse Supernovae (CCSNe) are explosive phenomena that may occur at the end of the life of massive stars, releasing over 99% of the energy through neutrino emission.

Core-collapse Supernovae [PDF]

open access: yesProceedings 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

Computational models of stellar collapse and core-collapse supernovae

open access: yesJournal of Physics: Conference Series, 2009
Core-collapse supernovae are among Nature's most energetic events. They mark the end of massive star evolution and pollute the interstellar medium with the life-enabling ashes of thermonuclear burning. Despite their importance for the evolution of galaxies and life in the universe, the details of the core-collapse supernova explosion mechanism remain ...

Multiwavelength View of Circumstellar Interaction in Supernovae

open access: yesUniverse
The interaction of post-explosion supernova ejecta with the surrounding circumstellar medium creates emissions across the electromagnetic spectrum. Since the circumstellar medium is created by the mass lost from the progenitor star, it carries tell-tale ...

Hydrodynamic Mixing of Accretion Disk Outflows in Collapsars: Implications for r-process Signatures

open access: yesThe Astrophysical Journal, 2023
The astrophysical environments capable of triggering heavy-element synthesis via rapid neutron capture (the r -process) remain uncertain. While binary neutron star mergers (NSMs) are known to forge r -process elements, certain rare supernovae (SNe) have ...
