Core-Collapse Supernovae (CCSNe) are violent explosions that occur at the end of the evolution of massive stars. After decades of research the detailed mechanism behind the explosion is still not fully understood. To investigate global properties of these events for a large sample of progenitor stars, multi-dimensional simulations are computationally too demanding and thus one has to rely on one-dimensional simulations in order to study large samples of progenitors. The PUSH method represents a suitable parametrized framework to investigate the neutrino-driven mechanism in spherically symmetric simulations to efficiently study many important aspects of CCSNe: the effects of the shock passage through the star, explosive nucleosynthesis and the progenitor-remnant connection. After calibrating the method to SN1987A and other observed CCSNe we explore a large mass range of available solar metallicity progenitors and investigate their explodability and the resulting explosion properties.
