摘要
对超新星前身星模型Ws12M⊙的瞬时爆发进行了数值模拟,讨论了压强梯度对超新星瞬时爆发能量的影响.数值分析发现增加压强梯度对压强本身修改不大,但爆发能量对压强梯度很敏感,无论在坍缩、反弹或传播过程中,压强梯度增加都会使瞬时爆发能量有很大的提高.
The supernova prompt explosion of a progenitor model Ws12M⊙ is simulated. The effect of pressure gradient on the prompt explosion energy of supernova is discussed. Numerical analysis indicates that the explosion energy is sensitive to the increasing of pressure gradient which has minor influence on the pressure, At collapse, bounce or propagation stage, the increasing of pressure gradient can improve the explosion energy obviously.
