Inferring Type II-P Supernova Progenitor Masses from Plateau Luminosities
Brandon L. Barker, Evan P. O'Connor, Sean M. Couch
Connecting observations of core-collapse supernova explosions to the properties of their massive star progenitors is a long-sought, and challenging, goal of supernova science. Rece…
A Parameterized Neutrino Emission Model to Study Mass Ejection in Failed Core-collapse Supernovae
A. S. Schneider, E. O'Connor
Some massive stars end their lives as \textit{failed} core-collapse supernovae (CCSNe) and become black holes (BHs). Although in this class of phenomena the stalled supernova shock…
Impact of Rotation on the Multimessenger Signatures of a Hadron-quark Phase Transition in Core-collapse Supernovae
Shuai Zha, Evan O'Connor
We study the impact of rotation on the multimessenger signals of core-collapse supernovae (CCSNe) with the occurrence of a first-order hadron-quark phase transition (HQPT). We simu…
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…
Detectability of neutrino-signal fluctuations induced by the hadron-quark phase transition in failing core-collapse supernovae
Zidu Lin, Shuai Zha, Evan P. O'Connor +1
We introduce a systematic and quantitative methodology for establishing the presence of neutrino oscillatory signals due to the hadron-quark phase transition (PT) in failing core-c…
Comparison of Electron Capture Rates in the N=50 Region using 1D Simulations of Core-collapse Supernovae
Zac Johnston, Sheldon Wasik, Rachel Titus +4
Recent studies have highlighted the sensitivity of core-collapse supernovae (CCSNe) models to electron-capture (EC) rates on neutron-rich nuclei near the N=50 closed-shell region.…
