论文摘要
开普勒太空望远镜的K2任务提供了一种独特的可能性，可以检查银河系和半乳酸外部的来源，并具有高节奏光度法。除了在靶向星系中检测到的众多超新星和类星体外，开普勒很可能偶然地观察到整个K2的许多瞬变。这些事件可能会发生在背景像素中，恰好围绕科学目标。分析背景像素的可能性有可能对每个广告系列进行几个方程的高节奏调查进行高节奏调查。我们证明了独立恢复K2瞬变（例如KSN 2015k和SN 2018OH）的能力。通过这项调查，我们希望检测到许多瞬变，并确定终身$ \ leq1 $ DAY的第一个瞬变汇率。
The K2 mission of the Kepler Space Telescope offers a unique possibility to examine sources of both Galactic and Extra-galactic origin with high cadence photometry. Alongside the multitude of supernovae and quasars detected within targeted galaxies, it is likely that Kepler has serendipitously observed many transients throughout K2. Such events will likely have occurred in background pixels, coincidentally surrounding science targets. Analysing the background pixels presents the possibility to conduct a high cadence survey with areas of a few square degrees per campaign. We demonstrate the capacity to independently recover key K2 transients such as KSN 2015K and SN 2018oh. With this survey, we expect to detect numerous transients and determine the first comprehensive rates for transients with lifetimes $\leq1$ day.
