It Takes Two: nucleosynthesis in core-collapse supernova simulations of binary-star progenitors
Gaétan Jalin, Almudena Arcones, Evan P. O'Connor +2
Binary interaction is common amongst massive stars and can significantly alter their pre-supernova structure and composition. This has important consequences for the nucleosyntheti…
Three-dimensional Core-Collapse Supernova Simulations: From shell burning to shock revival
Haakon Andresen, Evan P. O'Connor, C. E. Fields +1
The outcome of core-collapse supernova simulations depends sensitively on the multi-dimensional structure of the progenitor star at the onset of collapse. We perform three-dimensio…
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…
Neutrino Heating in 1D, 2D, and 3D core-collapse supernovae: characterizing the explosion of high-compactness stars
Luca Boccioli, David Vartanyan, Evan P. O'Connor +1
Massive stars can end their lives with a successful supernova explosion (leaving behind a neutron star or, more rarely, a black hole), or a failed explosion that leaves behind a bl…
Quantifying the Impact of the Si/O Interface in CCSN Explosions Using the Force Explosion Condition
Luca Boccioli, Mariam Gogilashvili, Jeremiah Murphy +1
The explosion mechanism of a core-collapse supernova is a complex interplay between neutrino heating and cooling (including the effects of neutrino-driven convection), the gravitat…
