Ib/c型和II型超新星及其宿主星系的统计研究

The statistical investigation of type Ib/c and II supernovae and their host galaxies

A. A. Hakobyan

摘要:

本文对Ib/c型和II型超新星的性质及其旋涡星系的积分参数进行了统计研究。对数据样本进行了一元统计和多元统计分析。发现Ib/c超新星比II型超新星更集中于星系中心。活动星系中Ib/c型和II型超新星的径向距离R(SN)/R(25)的分布比正常星系中更集中于中心。这种效应对于Ib/c型超新星比II型超新星更强。

英文摘要:

This is a statistical study of the properties of type Ib/c and II supernovae and of the integral parameters of their spiral host galaxies. The methods of one-dimensional and multivariate statistics were applied to the data sample. It was found that the Ib/c supernovae are more concentrated radially toward the centers of the galaxies than those of type II. The distributions of the radial distances R(SN)/R(25) for the type Ib/c and II supernovae in active galaxies are more concentrated toward the center than in normal galaxies. This effect is stronger for type Ib/c than for type II supernovae.
