几乎所有核心坍缩超新星的外观都在很大程度上受到其前身与紧密双星伴星之间相互作用的影响。利用全面、先进的单星和双星恒星演化模型网格，预测了超新星类型的相对频率及其主要特性的分布函数。研究了与附近星际物质相互作用的超新星，即在正在进行的双星质量转移过程中爆炸的超新星，发现它们约占所有核心坍缩超新星的5%，与观测结果一致。还研究了新生致密天体与伴星之间的相互作用，这可能产生类似于SN2022jli中看到的可观测特征。这些超新星可能占所有贫氢核心坍缩超新星的3%至27%。这些结果将有助于制定在过去和未来搜索中识别此类超新星的策略，这将有助于限制单星和双星演化模型中不确定的物理过程。
英文摘要
The appearance of nearly all core-collapse (CC) supernovae (SNe) is largely affected by the interaction between their progenitors and a close binary companion. Using a comprehensive, state-of-the-art grid of single- and binary stellar evolution models, the relative frequencies of SN types are predicted, as well as the distribution functions of their main properties. SNe that interact with nearby circumstellar material are included, namely those that explode during ongoing binary mass transfer, and are found to account for ~5% of all CCSNe, consistently with observations. The interaction between the newly born compact object and the companion is also investigated, which may produce observable signatures similar to those seen in SN2022jli. These SNe could account for between 3% and 27% of all H-poor CCSNe. These results will help develop strategies for identifying such supernovae in past and future searches, which will help to constrain uncertain physics in single and binary evolution models.
