Isosurfaces of mass fractions of (upper panels) and ⁴⁴Ti (lower panels) from different viewing angles for model W15-2-cw-IIb at t = 20.5 h after core bounce (from Wongwathanarat et al. 2017). The isosurfaces correspond to a value of mass fraction which is at 30% of the peak mass fraction of each species. The colors give the radial velocity in units of 1000 km s⁻¹ on the isosurface; the color coding is defined at the bottom of each panel.
