Comparing Early Evolution of Flames in X-ray Bursts in Two and Three Dimensions
arXiv:2303.17077 · doi:10.3847/1538-4357/ace04e
Abstract
We explore the early evolution of flame ignition and spreading on the surface of a neutron star in three-dimensions, in the context of X-ray bursts. We look at the nucleosynthesis and morphology of the burning front and compare to two-dimensional axisymmetric simulations to gauge how important a full three-dimensional treatment of the flame is for the early dynamics. Finally, we discuss the progress toward full-star resolved flame simulations.
