银道面附近若干天区变星搜寻

Variable Star Searching in Several Areas Near the Milky Way Disc

对新疆天文台南山1 m大视场天文望远镜观测的历史数据进行细致的数据挖掘,发现了百余颗变源。数据处理流水线为新疆天文台时域巡天数据处理包,该处理包同时考虑了测光系统内部权重和相关性,并结合快速混合算法编写。除去已知的变源,又发现了很多新的变源。对新变源证认的过程中,将结果与LAMOST,GCVS,VSX,Gaia DR2等星表进行交叉。在讨论部分,对各星表的使用情况给出了说明。最后发现这些新变源绝大部分是食双星,少部分是脉动变星,并有一颗表现相对复杂的变源。

In the history of the observation of Nanshan One meter widely-field telescope located at NanShan station of Xingjiang Astronomical Observatiories(XAO),we carried out detailed data mining and found more than a hundred variable sources.The data processing pipeline is the XAO time domain survey data processing package,which considers the internal weight and correlation of the metering system,and is written in combination with the fast hybrid algorithm.Removing the known sources,we found new sources.In the process of identifying new sources,we intersected the results with LAMOST,GCVS 5.1,VSX,Gaia DR2 and other star tables,and explained the results of each star table.In the end,most of them were binary stars,a few were pulsating variable stars,and there was a strange variable source.
