Slices in the YZ plane for Models BV (top row) and B0 (bottom row) at t = 0.1, 0.2, and 0.3 s, from left to right. The red line is the X(C ¹²) = 0.45 isocontour marking the flame surface. The color plot is the fluid speed, which spans, logarithmically, from less than 10 km s ⁻¹ (black) to 10 ⁴ km s ⁻¹ (white). The center of the bottom edge of each panel is at the center of the white dwarf, and all panels have a spatial scale of 280 km on a side. For the BV models (top row), there is a significant non-radial component to the velocity field, as evident by distortion of the flame surface to the upper left of the frames.
