We present a new series of supernova neutrino light curves and spectra calculated by numerical simulations for a variety of progenitor stellar masses ( 13- 50 M _ { \odot } ) and metallicities ( Z = 0.02 and 0.004 ) , which would be useful for a broad range of supernova neutrino studies , e.g. , simulations of future neutrino burst detection by underground detectors , or theoretical predictions for the relic supernova neutrino background .
To follow the evolution from the onset of collapse to 20 s after the core bounce , we combine the results of neutrino-radiation hydrodynamic simulations for the early phase and quasi-static evolutionary calculations of neutrino diffusion for the late phase , with different values of shock revival time as a parameter that should depend on the still unknown explosion mechanism .
We here describe the calculation methods and basic results including the dependence on progenitor models and the shock revival time .
The neutrino data are publicly available electronically .
