Bolometric luminosity for neutrinos of each species as a function of time for the simulations with (pink) and without (teal) oscillations. From left to right, each panel shows the luminosity from νe, ﹩{\bar{\nu }}_{e}﹩, νX, and ﹩{\bar{\nu }}_{X}﹩as dashed lines, as well as the total neutrino luminosity as solid lines. Oscillations systematically suppress electron flavors and enhance heavy flavors. Furthermore, between ∼3 and ∼60 ms, the total luminosity with FFCs exceeds the luminosity without, suggesting that the disk is more efficiently cooled.
