The electron capture rates during the collapse of a stellar core dominate the deleptonization and, therefore, describe the bounce shock’s location and energy, which should provide unique multimessenger signals that could be used as a constraint in further observations. In this work, we use a parametrized deleptonization formula to investigate the impact of deleptonization on the explodability and multimessenger signals of core-collapse supernovae via two-dimensional hydrodynamics simulations with neutrino transport.
