Molecular Environments of SNRs

Yang Chen, Bing Jiang, Ping Zhou, Yang Su, Xin Zhou, Hui Li, Xiao Zhang

摘要:

大约有70个银河系超新星遗迹(SNRs)现在被证实或建议与分子云(MC)有物理接触,并有六种多波长观测证据。最近详细的CO线光谱映射的一系列SNRs显示,他们在分子气体的空腔,这意味着祖细胞可能发挥的作用。我们预测在分子环境中的主序OB星的风泡大小和恒星质量之间的线性相关性,并讨论其对超新星祖先的影响。SNR的分子环境可以作为一个很好的探针的γ射线产生的强子相互作用的加速质子,本文还讨论了γ射线发射的MCs的扩散质子从SNR冲击逃逸。

英文摘要:

There are about 70 Galactic supernova remnants (SNRs) that are now confirmed or suggested to be in physical contact with molecular clouds (MCs) with six kinds of evidence of multiwavelength observations. Recent detailed CO-line spectroscopic mappings of a series of SNRs reveal them to be in cavities of molecular gas, implying the roles the progenitors may have played. We predict a linear correlation between the wind bubble sizes of main-sequence OB stars in a molecular environment and the stellar masses and discuss its implication for supernova progenitors. The molecular environments of SNRs can serve as a good probe for the gamma-rays arising from the hadronic interaction of the accelerated protons, and this paper also discusses the gamma-ray emission from MCs illuminated by diffusive protons that escape from SNR shocks.
