We are modeling mixed H/He X-ray bursts with our low Mach number hydrodynamics code Maestro. The nucleosynthesis is described by a 10-nuclei network that approximates hot-CNO, 3-alpha, and rp-process breakout. These simulations are done in a plane-parallel geometry, with a 6 cm resolution. These calculations follow on from our initial pure He simulations. Our two-dimensional results are described in the following papers:
Most recently, we've begun working on three-dimensional simulations:
