Abstract
An 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 () is short because high-density effects suppress our neutrino opacities. After a short phase of accretion-enhanced luminosities (), luminosity equipartition among all species becomes almost perfect and the spectra of and very similar, ruling out the neutrino-driven wind as -process site. We also discuss consequences for neutrino flavor oscillations.
