在恆星演化的末期，因重力而造成的核心坍縮，在這期間，電子捕獲的過程主導著核心的去輕子化，因此描述了反彈衝擊的位置及能量，而這些變化也會影響其多信使信號，可使我們在未來觀測超新星爆炸中，提供相當的資訊。在我們的研究當中，我們將去輕子化的公式參數化，並透過微中子轉移的二維流體力學模擬，來研究去輕子化在不同的恆星轉速時所造成的影響，包含其核心的變化，或是來自核心坍縮超新星重力波的訊號。

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.
