All-Sky Automated Survey for Supernovae: Big Science with Small Telescopes

即使在今天，也只有人眼才能监视整个夜空。没有光学测量频繁地成像和记录整个天球，寻找发生在我们宇宙中的瞬时、可变、有时甚至是暴力的事件。“全天超新星自动测量”(ASAS-SN)将每隔一晚自动测量整个可见天空。ASS-SN已经产生了源源不断的重要发现.ASS-SN还将为下一代时间域天文学家提供一个重要的培训基地，这一领域最终将被大型天文望远镜改变。这一提议的主要科学目标是显著增强我们对超新星的理解，无论是核心塌缩还是热核。这个团队将完成对明亮的附近超新星的无偏见普查，他们将详细研究这些事件及其东道主。ASS-SN目前正在进行所有明亮(17 MAG)SNE发现的50%以上，并回收其余大部分。明亮的和附近的SNE是由这项高频率调查早期发现的，特别有价值，因为它们和它们的宿主星系很容易用小型(1-2米)望远镜进行研究。AAS-SN应该导致新的、无偏见的超新星速率的推导，并更好地理解超新星的性质作为恒星年龄和金属丰度的函数。这项调查将公开发布数据，已经包括一个临时列表，刚刚发布的“AAS-SN CV巡逻”，以及未来的“AAS-SN巡逻”的不断更新的光线曲线的其他有趣的对象类别。变星的全天星表也将逐步发布。

Even in the present day, only human eyes monitor the entire night sky. There is no optical survey that frequently images and records the entire celestial sphere, seeking out the transient, variable, and sometimes violent events that occur in our Universe. The "All-Sky Automated Survey for Supernovae" (ASAS-SN) will automatically survey the entire visible sky every other night. ASAS-SN is already producing a steady stream of important discoveries. ASAS-SN will also provide a critical training ground for the next generation of time-domain astronomers, a field that will eventually be transformed by the Large Synoptic Survey Telescope.The major scientific goal of this proposal is to significantly enhance our understanding of supernovae, both core-collapse and thermonuclear. This team will complete an unbiased census of bright, nearby supernovae, and they will study these events and their hosts in detail. ASAS-SN is currently making more than 50% of all the bright (17 mag) SNe discoveries and recovering most of the rest. Bright and nearby SNe, discovered early by this high-cadence survey, are especially valuable, as they and their host galaxies are easy to study using small (1-2m) telescopes. ASAS-SN should lead to new, unbiased derivations of supernova rates and a better understanding of supernova properties as a function of stellar age and metallicity. This survey will be publicly releasing data, already including a transient list, just released "ASAS-SN CV Patrol", and future "ASAS-SN Patrols" of continuously updated light curves for other interesting classes of objects. All-sky catalogues of variable stars will be gradually released as well.
