Abstract: I will present the results of spherically symmetric explosion simulations for a set of 101 progenitor stars of solar metallicity, performed with the aim of better understanding the connection between the properties of progenitor stars and those of core-collapse supernovae and their remnants. The explosions were initiated by means of a neutrino-heating scheme that depends on parametrized neutrino quantities (luminosities and mean spectral energies). The evolution of the models and the explosive nucleosynthesis were followed beyond shock breakout from the stellar surface. Because of strong star-to-star variations of the progenitor structure at the onset of collapse, we find a great variability of supernova properties (such as explosion energy, compact remnant mass, and ejected nickel mass) even in narrow progenitor-mass windows. This novel approach allows to establish better links of theoretical explosion models with observations.
