SNe Ib/c的位置及其与WR星和伽玛暴的比较
The locations of SNe Ib/c and their comparison to those of WR stars and GRBs
摘要：
长伽玛暴和剥离超新星的位置进行了比较，他们的青睐的祖先，WR星，和他们的子类。与Leloudas等人（2010）相比，我们已经将具有合适WR数据的星系数量增加了一倍。在合并后的样本中，WC星被发现，平均而言，在明亮的位置比WN星。WN分布与SNe Ib的分布完全一致，而与SNe II、Ic和GRB的分布不一致。WC分布与SNe Ib和Ic一致。它与SNe II不一致，与GRB略微一致。此外，我们提出了一个光谱研究的SNe Ib/c的位置。在环境中的SNe Ic的平均金属丰度被认为是略高于SNe Ib，但差异很小，并不显着在我们的样本。假设SN区域是在恒星形成的瞬间爆发中形成的，我们发现它们中的一小部分看起来比为了从单个大质量恒星中托管SNe Ib/c所允许的年龄要大。在这个框架内，这些SNe必须来自较低质量的双星。
英文摘要：
The locations of long GRBs and stripped supernovae are compared to those of their favored progenitors, WR stars, and their sub-classes. Compared to Leloudas et al. (2010), we have doubled the number of galaxies with suitable WR data. In the combined sample, WC stars are found, on average, in brighter locations than WN stars. The WN distribution is fully consistent with the one of SNe Ib, while it is inconsistent with those of SNe II, Ic and GRBs. The WC distribution is both consistent with SNe Ib and Ic. It is inconsistent with SNe II, and marginally consistent with GRBs. Furthermore, we present a spectroscopic study of the locations of SNe Ib/c. The average metallicity in the environments of SNe Ic is found to be a little higher than for SNe Ib, but the difference is small and not significant within our sample. Under the assumption that the SN regions were formed in an instantaneous burst of star formation, we find that a fraction of them appear older than what is allowed in order to host SNe Ib/c from single massive stars. Within this framework, these SNe must come from lower mass binaries.
