Time evolution (indicated by color) of radial profiles of the electron fraction (Ye; top left), radial velocity (vr; top right), electron-neutrino rms energy (εrms(νe); bottom left), and electron-neutrino luminosity (L(νe); bottom right). The figure illustrates the collapse and postbounce evolution over a ±150 ms interval centered on core bounce. Curves represent snapshots spaced by 7.5 ms, with line color encoding time relative to bounce (blue: early prebounce; yellow: late postbounce), as shown by the color bar on the right.
