The Gravitational-Wave Power Gap in Core-Collapse Supernovae: Insights from 60 Axisymmetric Simulations
Haakon Andresen, Xingzao Li, Aurore Betranhandy +3
We analyse the gravitational-wave emission from 60 two-dimensional core-collapse supernova simulations. The models cover a range of progenitors and equations of state. We focus on…
A new approximation for heavy-lepton neutrino pair processes in simulations of core-collapse supernovae
Aurore Betranhandy, Evan O'Connor
In this paper, we present a new approximation for efficiently and effectively including heavy-lepton neutrino pair-production processes in neutrino transport simulations of core-co…
Variety of disc wind-driven explosions in massive rotating stars. II. Dependence on the progenitor
Ludovica Crosato Menegazzi, Sho Fujibayashi, Masaru Shibata +2
We assess the variance of supernova(SN)-like explosions associated with the core collapse of rotating massive stars into a black hole-accretion disc system under changes in the pro…
Neutrino Driven Explosions aided by Axion Cooling in Multidimensional Simulations of Core-Collapse Supernovae
Aurore Betranhandy, Evan O'Connor
In this study, we present the first multidimensional core-collapse supernovae (CCSNe) simulations including QCD axions in order to assess the impact on the CCSN explosion mechanism…
Equation of State Dependence of Gravitational Waves in Core-Collapse Supernovae
Oliver Eggenberger Andersen, Shuai Zha, André da Silva Schneider +3
Gravitational waves (GWs) provide unobscured insight into the birthplace of neutron stars (NSs) and black holes in core-collapse supernovae (CCSNe). The nuclear equation of state (…
Impact of neutrino pair-production rates in Core-Collapse Supernovae
Aurore Betranhandy, Evan O'Connor
In this paper, we present a careful study on the impact of neutrino pair-production on core-collapse supernovae via spherically-symmetric, general-relativistic simulations of two d…
Equation of State and Progenitor Dependence of Stellar-Mass Black-Hole Formation
A. S. Schneider, E. O'Connor, E. Granqvist +2
The core collapse of a massive star results in the formation of a proto-neutron star (PNS). If enough material is accreted onto a PNS it will become gravitationally unstable and fu…
