Low Mach number modeling of Type I X-ray burst deflagrations
The Low Mach Number Approximation (LMNA) is applied to 2D hydrodynamical modeling of Type I X-ray bursts on a rectangular patch on the surface of a non-rotating neutron star. Because such phenomena involve decidedly subsonic flows, the timestep increase offered by the LMNA makes routine simulations of these deflagrations feasible in an environment where strong gravity produces significant strat...
متن کاملLOW MACH NUMBER MODELING OF TYPE Ia SUPERNOVAE. I. HYDRODYNAMICS
We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and a savings in computer time compared with frequently used compre...
متن کاملLOW MACH NUMBER MODELING OF TYPE Ia SUPERNOVAE. III. REACTIONS
We continue the description of a lowMach number hydrodynamics algorithm for reacting, full star flows. Here we demonstrate how to accurately incorporate reactions using a second-order accurate Strang-splitting technique. We also improve the fidelity of the model by allowing the base state to evolve in response to large-scale convection as well as large-scale heating, taking care to account for ...

متن کاملLOW MACH NUMBER MODELING OF TYPE Ia SUPERNOVAE. II. ENERGY EVOLUTION
The convective period leading up to a Type Ia supernova (SN Ia) explosion is characterized by very low Mach number flows, requiring hydrodynamic methods well-suited to long-time integration. We continue the development of the lowMach number equation set for stellar-scale flows by incorporating the effects of heat release due to external sources. Low Mach number hydrodynamics equations with a ti...
