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…
Simulation to a Newborn Supernova Remnant from a Low-mass Iron Core Star
Sudarshan Neopane, Michael A. Sandoval, W. Raphael Hix +3
Supernova remnant observations show a high degree of asymmetry, mixing, and inhomogeneity. These asymmetries are seeded during the early seconds of the explosion and are further en…
Impacts of Multidimensional Progenitor Perturbations on Core-Collapse Supernova Explosions
Chien-Hui Chen, Eric J. Lentz, W. Raphael Hix +3
Numerical studies of core-collapse supernovae have demonstrated the importance of non-radial motions in pre-collapse progenitors on the explosion outcome. We use the CHIMERA neutri…
Low-Frequency Gravitational Waves in Three-Dimensional Core-Collapse Supernova Models
Colter J. Richardson, Anthony Mezzacappa, Kya Schluterman +5
We discuss the low-frequency gravitational wave signals from three state-of-the-art three-dimensional core-collapse supernova models produced with the \textsc{Chimera} supernova co…
Detecting Gravitational Wave Memory in the Next Galactic Core-Collapse Supernova
Colter J. Richardson, Haakon Andresen, Anthony Mezzacappa +5
We present an approach to detecting (linear) gravitational wave memory in a Galactic core-collapse supernova using current interferometers. Gravitational wave memory is an importan…
Approximating General Relativity in Core-Collapse Supernova Simulations
Steven A. Fromm, Vassilios Mewes, O. E. Bronson Messer +3
We present formulations of effective potentials suitable for approximating general relativistic effects in Newtonian simulations of core-collapse supernovae. Assuming a spherically…
