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…
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…
thornado+Flash-X: A Hybrid DG-IMEX and Finite-Volume Framework for Neutrino-Radiation Hydrodynamics in Core-Collapse Supernovae
Eirik Endeve, Vassilios Mewes, J. Austin Harris +15
We present neutrino-transport algorithms implemented in the toolkit for high-order neutrino-radiation hydrodynamics (thornado) and their coupling to self-gravitating hydrodynamics…
Crust composition and the Shallow Heat Source in KS 1731-260
R. Jain, E. F. Brown, H. Schatz +11
The presence of a strong shallow heat source of unknown origin in accreting neutron star crusts has been inferred by analyzing X-ray observations of their cooling in quiescence. We…
Hydrodynamic Predictions for the Next Outburst of T Coronae Borealis: It will be the Brightest Classical or Recurrent Nova Ever Observed in X-rays
S. Starrfield, M. Bose, C. E. Woodward +11
T Coronae Borealis (TCrB) is a recurrent nova (RN) with recorded outbursts in 1866, and 1946 and possible outbursts in 1217 and 1787. It is predicted to explode again in 2025 or 20…
