Temporal evolution of the explosion for the AWD3ddt model. Top panel: ignition configuration (t = 0 s) with a zoom-in on the ignition kernels. Lower panels: evolution of the deflagration ash (pink) and the detonation front (light blue). The dark blue surface indicates the outer boundary of the star. d denotes the size of the computational domain. The decrease in d is due to our nested-grid approach (Röpke et al. 2006).
