超新星母星系消光的径向依赖性

Radial Dependence of Extinction in Parent Galaxies of Supernovae

Dusan Onic, Bojan Arbutina, Dejan Urosevic

摘要:

在获得核坍缩(包括剥离包层)超新星(SNe)的真实绝对星等的过程中,灭绝问题是需要解决的最重要的问题。过去广泛使用的平面平行模型已被证明不能充分描述灭绝。我们试图应用另一种模型,该模型引入了超新星母星系消光的径向依赖性。为了计算我们银河系的消光,我们使用了两种不同的方法,并比较了所获得的结果。我们的分析主要集中在一个选定的样本的剥离包络SNe(Ib/c),我们发现内在的峰值绝对幅度$\mathrm{M}_{\mathrm{B}}^{0}=-17.80\pm 0.43$。

英文摘要:

The problem of extinction is the most important issue to be dealt with in the process of obtaining true absolute magnitudes of core-collapse (including stripped-envelope) supernovae (SNe). The plane-parallel model, widely used in the past, was shown not to describe extinction adequately. We try to apply an alternative model which introduces radial dependance of extinction in parent galaxies of supernovae. For calculating extinction in our Galaxy we use two different methods and compare the results obtained. Our analysis is primarily focused on a chosen sample of stripped-envelope SNe (Ib/c) for which we find intrinsic peak absolute magnitude $\mathrm{M}_{\mathrm{B}}^{0}=-17.80\pm 0.43$.
