Comparing Type Ia Supernova Hydrodynamical Simulations to X-ray Observations Using Comoving Formulation

Type Ia supernova explosions (SNe Ia) are high-energy astrophysical transients that are important for nucleosynthesis of iron group and intermediate mass elements, energizing turbulence in the interstellar medium, and measuring distances in the cosmos. The stellar progenitor systems and dynamics of SNe Ia are not well known but can be probed by X-ray observations of galactic supernova remnants. Simulating fully 3D models of SNe Ia from the exploding white dwarf star on the scale of kilometers through the remnant phase on the scale of parsecs is an incredibly demanding computational challenge. We are developing a method of solving the hydrodynamical simulations in a comoving, rather than inertial, reference frame using the open source hydrodynamic simulation framework FLASH-X. This comoving formulation will be made publicly available and will enable researchers to pursue “end to end” simulations of a wide variety of transients, including supernovae, kilonovae, and gamma ray bursts.
