一种确定初始爆炸能量的独特方法

A Unique Method to Determine SNe Initial Explosion Energy

Jian-Wen Xu, Hui-Rong Zhang

摘要:

确定单个超新星(SNe)的初始爆炸能量有几种不同的方法,本文用一种特殊的方法导出了壳型超新星遗迹(SNRs)的平均或典型爆炸能量。通过求解同一阶段壳型信噪比方程组,得到了距离($d$)、演化年龄($t$)等物理参数。假设SN的初始爆炸能量从$10^{48}$尔格到$10^{53}$尔格不等,导出了距离和年龄参数,并与已知参数进行了比较。从而得到了偏离最小时的SNe初始爆炸能量的最可能值,约为$10^{51}$尔格,与理论值吻合较好。

英文摘要:

There are several different methods to determine the individual supernovae (SNe) initial explosion energy, here we derive the average or typical explosion energy of shell-type supernova remnants (SNRs) in a particular way. By solving a group of equations pertaining to shell-type SNRs at the same stage we obtained some physical parameters, e.g. the distance ($d$), evolved age ($t$), etc.. Assuming series of different SN initial explosion energies ranging from $10^{48}$ ergs to $10^{53}$ ergs, we derived series of distance and age parameters with which compared already known ones. Thus the most likely value of the SNe initial explosion energy is obtained when the deviation is least, which equals to about $10^{51}$ ergs, in good agreement with the undertook value.
