TL;DR
This paper reports on multidimensional simulations of pair-instability supernovae using a new radiation-hydrodynamics code, focusing on fluid instabilities and a novel initial condition mapping method that ensures conservation across resolutions.
Contribution
It introduces a new multidimensional simulation approach and a mapping procedure that preserves physical quantities, advancing the modeling of pair-instability supernovae.
Findings
Fluid instabilities are studied in multiple spatial dimensions.
A new mapping procedure guarantees conservation at any resolution.
Preliminary results demonstrate the effectiveness of the approach.
Abstract
We present preliminary results from multidimensional numerical studies of pair instability supernova (PSN), studying the fluid instabilities that occur in multiple spatial dimensions. We use the new radiation-hydrodynamics code, CASTRO, and introduce a new mapping procedure that defines the initial conditions for the multidimensional runs in such a way that conservation of physical quantities is guaranteed at any level of resolution.
