During the collapse of a stellar core, the electron capture process dominates the core deleptonization and, therefore, describes the location and energy of the bounce shock, which should provide unique multimessenger signals that could be used as a constraint in future observations. In this work, we use a parametrized deleptonization formula to investigate the impact of deleptonization and stellar rotation on the gravitational wave signals from core-collapse supernovae via two-dimensional hydrodynamics simulations with neutrino transport. In particular, we focus on gravitational-wave emissions at around core bounce and during the prompt convection phase.
