银河系或其卫星中的下一个核心坍缩超新星将代表着一个千载难逢的机会，可以获得有关星星爆炸的详细信息，并为各种领域提供重要的科学见解，因为其中发现了极端条件。我们银河系中的超新星不仅在人类的时间尺度上很罕见，而且还发生在计划外的时间，因此做好准备并使用所有可用的仪器来捕捉事件中所有可能的信息至关重要。一个潜在的恒星爆炸的第一个迹象将是一个明亮的中微子爆发的到来。全球多个探测器的观测可以为随后的电磁烟花提供早期预警，并向其他具有重要背景的探测器发出信号，以便他们可以存储最新数据。超新星早期预警系统（SNEWS）自2005年以来一直以自动模式在中微子实验之间进行简单的巧合。在当前的多信使天文学时代，SNEWS有新的机会来优化对下一个银河系超新星的科学敏感性，而不仅仅是简单的早期警报。本文件是2019年6月针对SNEWS 2.0设计的研讨会的产物，SNEWS 2.0是一个升级的SNEWS，具有增强的功能，利用即时中微子探测的独特优势，最大限度地利用从这样一个有价值的事件中获得的科学。
The next core-collapse supernova in the Milky Way or its satellites will represent a once-in-a-generation opportunity to obtain detailed information about the explosion of a star and provide significant scientific insight for a variety of fields because of the extreme conditions found within. Supernovae in our galaxy are not only rare on a human timescale but also happen at unscheduled times, so it is crucial to be ready and use all available instruments to capture all possible information from the event. The first indication of a potential stellar explosion will be the arrival of a bright burst of neutrinos. Its observation by multiple detectors worldwide can provide an early warning for the subsequent electromagnetic fireworks, as well as signal to other detectors with significant backgrounds so they can store their recent data. The supernova early warning system (SNEWS) has been operating as a simple coincidence between neutrino experiments in automated mode since 2005. In the current era of multi-messenger astronomy there are new opportunities for SNEWS to optimize sensitivity to science from the next galactic supernova beyond the simple early alert. This document is the product of a workshop in June 2019 towards design of SNEWS 2.0, an upgraded SNEWS with enhanced capabilities exploiting the unique advantages of prompt neutrino detection to maximize the science gained from such a valuable event.
