距离两个银河系超新星遗迹:G32-0.1和G346 .6-0.2

Distances to Two Galactic Supernova Remnants: G32.8-0.1 and G346.6-0.2

Jian-Wen Xu, Hui-Rong Zhang

摘要:

利用银河系自转曲线导出的银河系超新星遗迹(SNR)G32.8 $-$ 0.1的近运动学距离为5.5kpc,远运动学距离为8.8kpc。本文通过求解壳型残留物在绝热相和辐射相的方程组,确定了残留物的距离为8.8kpc。对于SNR G346.6 $-$ 0.2,我们确定其距离也是较远的11 kpc,而不是较近的5.5 kpc。

英文摘要:

There are either a near kinematic distance of 5.5 kpc or a far distance of 8.8 kpc for a Galactic supernova remnant (SNR) G32.8$-$0.1 derived by using the rotation curve of the Galaxy. Here we make sure that the remnant distance is the farther one 8.8 kpc through solving a group of equations for the shell-type remnants separately at the adiabatic-phase and the radiative-phase. For SNR G346.6$-$0.2 we determine its distance also the farther one 11 kpc rather than the nearer one 5.5 kpc.
