Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure
arXiv:1912.04956 · doi:10.3847/1538-4357/ab80bc
Abstract
We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propagation are performed through a rotating plane-parallel atmosphere, exploring the structure of the flame. We discuss the approximations needed to capture the length and time scales at play in an X-ray burst and describe the flame acceleration observed. Our studies complement other multidimensional studies of burning in X-ray bursts.
