Revival of The Stalled Core-Collapse Supernova Shock Triggered by Precollapse Asphericity in the Progenitor Star
Sean M. Couch, Christian D. Ott
Multi-dimensional simulations of advanced nuclear burning stages of massive stars suggest that the Si/O layers of presupernova stars harbor large deviations from the spherical symm…
High-Resolution Three-Dimensional Simulations of Core-Collapse Supernovae in Multiple Progenitors
Sean M. Couch, Evan P. O'Connor
Three-dimensional simulations of core-collapse supernovae are granting new insight into the as-yet uncertain mechanism that drives successful explosions. While there is still debat…
Multidimensional Simulations of Rotating Pair Instability Supernovae
E. Chatzopoulos, J. C. Wheeler, S. M. Couch
We study the effects of rotation on the dynamics, energetics and Ni-56 production of Pair Instability Supernova explosions by performing rotating two-dimensional ("2.5-D") hydrodyn…
An Improved Multipole Approximation for Self-Gravity and Its Importance for Core-Collapse Supernova Simulations
Sean M. Couch, Carlo Graziani, Norbert Flocke
Self-gravity computation by multipole expansion is a common approach in problems such as core-collapse and Type Ia supernovae, where single large condensations of mass must be trea…
Radiation Transport for Explosive Outflows: A Multigroup Hybrid Monte Carlo Method
Ryan T. Wollaeger, Daniel R. van Rossum, Carlo Graziani +4
We explore Implicit Monte Carlo (IMC) and Discrete Diffusion Monte Carlo (DDMC) for radiation transport in high-velocity outflows with structured opacity. The IMC method is a stoch…
