Long-term Simulations of Multi-Dimensional Core-collapse Supernovae: Implications for Neutron Star Kicks

Understand

Core-collapse supernovae (CCSNe) are the final stage of massive stars, marking the birth of neutron stars (NSs).

• The aspherical mass ejection drives a natal kick of the forming NS.
• In this work we study the properties of the NS kick based on our long-term hydrodynamics CCSN simulations.
• We perform two-dimensional (2D) simulations for ten progenitors from a 10.8 to 20 $\, M_{\odot}$ star covering a wide range of the progenitor's compactness parameter, and two three-dimensional (3D) simulations for an 11.2 $\, M_{\odot}$ star.
