Title: Toward Resolved Simulations of Burning Fronts in Thermonuclear X-ray Bursts

Abstract

We discuss the challenges of modeling X-ray bursts in multi-dimensions, review the different calculations done to date, and discuss our new set of ongoing simulations. We also describe algorithmic improvements that may help in the future to offset some of the expense of these simulations, and describe what may be possible with exascale computing.
