论文摘要
二元相互作用，尤其是传质和合并，可以强烈影响巨大的恒星的演变，并改变其最终特性和超新星的发生。在这里，我们研究了二元相互作用如何影响中微子弥漫通量的预测。通过执行包括二进制相互作用的处方（包括二进制相互作用的处方）的出色种群合成，我们表明，与没有二进制考虑因素的估计值相比，弥漫性超新星中微子背景的检测率提高了15％-20％。由于目前对快速旋转的碳 - 氧气核心的演变而稀疏的知识，尤其是那些由于白色矮人附近的合并到核心塌陷边界而产生的，因此出现了明显的不确定性来源。如果忽略了后旋转系统中旋转的效果，则增强效应可能会高达几％，或者如果推断出趋势，则高达75％。我们的估计旨在强调二元效应可能很重要。
Binary interactions, especially mass transfer and mergers, can strongly influence the evolution of massive stars and change their final properties and the occurrence of supernovae. Here, we investigate how binary interactions affect predictions of the diffuse flux of neutrinos. By performing stellar population syntheses including prescriptions for binary interactions, we show that the resulting detection rates of the diffuse supernova neutrino background is enhanced by 15%-20% compared to estimates without binary considerations. A source of significant uncertainty arises due to the presently sparse knowledge of the evolution of rapidly rotating carbon-oxygen cores, especially those created as a result of mergers near the white dwarf to core collapse boundary. The enhancement effect may be as small as a few percent if the effects of rotation in postmerger systems are neglected, or as large as 75% if trends are extrapolated. Our estimates serve to highlight that binary effects can be important.
