Universal relations applied to proto-neutron star generated gravitational waves from three-dimensional core collapse supernova simulations
R. Daniel Murphy, Anthony Mezzacappa, Colter J. Richardson +3
Using asteroseismology techniques, several relations have been developed that relate the quasi-normal, non-radial oscillation mode frequencies of the proto-neutron star (PNS) to th…
GenASiS: General Astrophysical Simulation System. II. Self-gravitating Baryonic Matter
Christian Y. Cardall, Reuben D. Budiardja, R. Daniel Murphy +1
GenASiS (General Astrophysical Simulation System) is a code being developed initially and primarily, though not exclusively, for the simulation of core-collapse supernovae on the w…
Gravitational Waves as a Probe of Core Collapse Supernova Progenitor Structure
R. Daniel Murphy, Elle Brinkman, Colter J. Richardson +5
We present the gravitational wave predictions from two-dimensional core collapse supernova (CCSN) simulations initiated from two nearly identical progenitors that have significantl…
Core Collapse Supernova Gravitational Wave Sourcing and Characterization based on Three-Dimensional Models
R. Daniel Murphy, Anthony Mezzacappa, Eric J. Lentz +1
We present for the first time an analysis of high-frequency gravitational wave (GW) emission from proto-neutron stars (PNS) in core collapse supernovae (CCSN) that combines spatial…
