Description

Evolution of the abundance of carbon-12 over the course of the mixing process that occurs during a nova explosion at the interface between a white dwarf and the envelope transferred by its companion. The video shows the appearance of hydrodynamic instabilities (Kelvin-Helmholtz type) in the form of filaments, which are responsible for the mixing process. At the end of the simulation, carbon and oxygen enrichment reaches 20% by mass. The simulations were run on the MareNostrum supercomputer at the BSC and required 150,000 CPU hours.
