II型超新星瞬发爆炸模型的激波传播

Shock Propagation in the Prompt Explosion Model of SN II

本文专门讨论II型超新星瞬发爆炸模型中的激波形成点、激波波阵面的位置、激波速度和激波能量等一系列的问题 .研究发现在外星核区除存在首级激波外 ,还存在次级激波 ;激波波阵面的准确位置应在熵变化的最大点和外星核区中人为粘性压的最大点之间 ;

This paper is devoted to a discussion of some problems concerning the shock wave in our supernova model, including the positions of the formation point and shock front, shock velocity and shock energy. We find that (1) there exists a second shock wave besides the first one in the outer core; (2) the precise position of the shock front is located between the maximum entropy and the maximum pseudo viscosity regions. In addition we derive the relations between the different definitions of shock energy.
