Using Adaptive Nested Mesh Code HydroBox3D for Numerical Simulation of Type Ia Supernovae: Merger of Carbon-Oxygen White Dwarf Stars, Collapse, and Non-Central Explosion

The paper presents the results of mathematical modeling of the three main stages of the explosion of supernovae of type Ia (SNIa): merging of white dwarfs, collapse and noncentral explosion. In the fusion problem shown the general fall mechanism of the satellite star onto the central star. At the modeling of the collapse process, the behavior of various types of energies is investigated. Also shown is the qualitative dynamics of a noncentral of a star explosion, whose source is the characteristic value of the energy released by the reaction C + C. The simulation was carried out using the original HydroBox3D code, in which the concept of adaptive nested mesh is implemented.
