论文摘要

我们进行了对Zwicky Transient设施(ZTF)在2019年和2020年观察到的彗星P/2019 LM $ $ _4 $(PALOMAR)的初步分析。我们发现,2019年的彗星在2019年发现了彗星的发现,并且2020年的回收率很大程度上归因于两个单独的销售,这是$ \ gtrsim $ \ gtrsim $ gtrsim $ gtrs $ gtrs $ gtrs $ gtrs。爆发发生在2019年4月底至2019年5月上旬以及2020年5月8.31和9.52 UTC之间。

We present a preliminary analysis of comet P/2019 LM$_4$ (Palomar) as observed by the Zwicky Transient Facility (ZTF) survey in 2019 and 2020. We find that the discovery of the comet in 2019 and the recovery in 2020 is largely attributed to two separate outbursts that are $\gtrsim2$ and $\gtrsim3.9$ mag in strength. The outbursts occurred around the end of April to early May of 2019 as well as between 2020 May 8.31 and 9.52 UTC, respectively.
