Abstract

An 8.8M electron-capture supernova was simulated in spherical symmetry consistently from collapse through explosion to essentially complete deleptonization of the forming neutron star. The evolution time (9s) is short because high-density effects suppress our neutrino opacities. After a short phase of accretion-enhanced luminosities (200ms), luminosity equipartition among all species becomes almost perfect and the spectra of ν¯e and ν¯μ,τ very similar, ruling out the neutrino-driven wind as r-process site. We also discuss consequences for neutrino flavor oscillations.
