Identify main-sequence binaries from the Chinese Space Station Telescope Survey with machine learning
Jia-jia Li, Jin-liang Wang, Kai-fan Ji +4
The statistical properties of double main sequence (MS) binaries are very important for binary evolution and binary population synthesis. To obtain these properties, we need to ide…
LEIA discovery of the longest-lasting and most energetic stellar X-ray flare ever detected
Xuan Mao, He-Yang Liu, Song Wang +40
The Lobster Eye Imager for Astronomy (LEIA) detected a new X-ray transient on 2022 November 7, identified as a superflare event occurring on a nearby K-type giant star HD 251108. T…
A Method of Rapidly Deriving Late-type Contact Binary Parameters and Its Application in the Catalina Sky Survey
JinLiang Wang, Xu Ding, JiaJia Li +3
With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released. Deriving parameters for CBs u…
The First Photometric Analysis of Two Low Mass Ratio Contact Binary Systems In TESS Survey
Qiyuan Cheng, Jianping XIong, Xu Ding +8
Low mass-ratio (q) contact binary systems are progenitors of stellar mergers such as blue straggles (BS) or fast-rotating FK Com stars. In this study, we present the first light cu…
