(a) Plots of the angle‐averaged d∊/dt at 137, 212, and 512 ms after bounce; d∊/dt is the net heating or cooling from electron neutrino and antineutrino absorption and emission. (b) Plots of the maximum net neutrino heating and maximum net neutrino cooling rates as a function of time during the course of our simulation. (c) Plots of the maximum net neutrino heating and maximum net neutrino cooling rates as a function of time during the critical 50–150 ms after bounce.
