论文摘要
自从SN 1987a成功检测到超新星中微子以来，已经过去了将近30年。在过去的几十年中，中微子检测技术已经取得了显着的进展，可以通过新来源检测中微子，从新来源，苏佩尔诺娃（PRE-SN）中微子。它们是在核心反弹之前从巨大的恒星中散发出来的。由于中微子自由地从核心中逃脱，因此他们直接携带有关恒星物理的信息。前中微子前中微子可能在验证我们对大型恒星的恒星进化的理解中起重要作用。此外，如果祖细胞位于我们附近，可以提前几天对超新星爆炸的观察结果，这可能会提前几天，使我们能够观察下一个银河系超新星。在这篇综述中，我们总结了从理论和观察的观点中总结了SN中微子研究的当前状态。
Almost 30 years have passed since the successful detection of supernova neutrinos from SN 1987A. In the last decades, remarkable progress has been made in neutrino detection technique, through which it may be possible to detect neutrinos from a new source, pre-supernova (pre-SN) neutrinos. They are emitted from a massive star prior to core bounce. Because neutrinos escape from the core freely, they carry information about the stellar physics directly. Pre-SN neutrinos may play an important role in verifying our understanding of stellar evolution for massive stars. Observations of pre-SN neutrinos, moreover, may serve as an alarm regarding a supernova explosion a few days in advance if the progenitor is located in our vicinity, enabling us to observe the next galactic supernova. In this review, we summarize the current status of pre-SN neutrino studies from both of the theoretical and observational points of view.
