A Three-Dimensional Exploration of Magnetic Fields, Rotation, and Shock Revival in a Core-Collapse Supernova Progenitor
Liubov Kovalenko, Evan O'Connor, Haakon Andresen +1
We present three-dimensional hydrodynamic and magnetohydrodynamic core-collapse supernova simulations of a rapidly rotating, high-compactness progenitor to investigate…
Black Hole Supernovae Outcomes Across a Wide Progenitor Range
Oliver Eggenberger Andersen, Evan O'Connor, Liubov Kovalenko +2
Black hole supernovae (BHSNe), the term we use for core-collapse events in which black hole (BH) formation occurs after shock revival but before the explosion is complete, have eme…
Enhanced antineutrino emission from decay in core-collapse supernovae with self-consistent weak decay rates
T. Dasher, A. Ravlić, S. Lalit +2
Nuclear weak-interaction rates are known to exert a prominent effect in the late-stages of stellar collapse. Despite their importance, most studies to date on core-collapse superno…
Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. II: Lightcurve Analysis
Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +18
The Zwicky Transient Facility Census of the Local Universe survey yielded a sample of 330 Type IIP supernovae (SNe) with well-constrained peak luminosities. In paper I (arXiv:2502.…
Black Hole Supernovae, their Equation of State Dependence and Ejecta Composition
Oliver Eggenberger Andersen, Evan O'Connor, Haakon Andresen +2
Recent literature on core-collapse supernovae suggests that a black hole (BH) can form within s of shock revival, while still culminating in a successful supernova. We ref…
Phase-transition-induced collapse of proto-compact stars and its implication for supernova explosions
Xu-Run Huang, Shuai Zha, Ming-chung Chu +2
A hadron-quark phase transition (PT) may trigger supernova explosions during stellar core collapse. However, both success and failure have occurred in previous attempts to explode…
Unveiling the Nature of Gravitational-Wave Emission in Core-collapse Supernovae with Perturbative Analysis
Shuai Zha, Oliver Eggenberger Andersen, Evan P. O'Connor
Gravitational waves (GWs) can provide crucial information about the central engines of core-collapse supernovae (CCSNe). In order to unveil the nature of GW emission in CCSNe, we a…
Gray Two-moment Neutrino Transport: Comprehensive Tests and Improvements for Supernova Simulations
Haakon Andresen, Evan P. O'Connor, Oliver Eggenberger Andersen +1
In this work we extended an energy-integrated neutrino transport method to facilitate efficient, yet precise, modeling of compact astrophysical objects. We particularly focus on co…
Nuclear pasta and supernova neutrinos at late times
C. J. Horowitz, D. K. Berry, M. E. Caplan +5
Nuclear pasta, with nucleons arranged into tubes, sheets, or other complex shapes, is expected in core collapse supernovae (SNe) at just below nuclear density. We calculate the add…
