The X-ray Emission Reveals the Coronal Activities of Semi-detached Binaries
Junhui Liu, Jianfeng Wu
X-ray emission is an important tracer of stellar magnetic activity. We carried out a systematic correlation analysis for the X-ray luminosity , bolometric luminosit…
Wide binaries with white dwarf or neutron star companions discovered from Gaia DR3 and LAMOST
Xinlin Zhao, Huijun Mu, Song Wang +12
Gaia DR3 mission has identified and provided about 440,000 binary systems with orbital solutions, offering a valuable resource for searching binaries including a compact component.…
KIC 12602250: A low-amplitude Double-mode Scuti star with Amplitude Modulation
Chenlong Lv, Ali Esamdin, Xiangyun Zeng +3
We propose for the first time that KIC 12602250 is a low-amplitude radial double-mode Scuti star with amplitude modulation. The detailed frequency analysis is given for the lig…
Investigating Variable Stars in the Open Cluster NGC 1912 and Its Surrounding Field
Chunyan Li, Ali Esamdin, Yu Zhang +6
In this work, we studied the variable stars in the open cluster NGC 1912 based on the photometric observations and DR2 data. More than 3600 CCD frames in B, V, R filters wer…
KIC 8840638: A new eclipsing binary consisting of Scuti-type oscillations with an extremely cold companion star
Tao-Zhi Yang, Zhao-Yu Zuo, Jun-Hui Liu +1
In this paper, we analyze the light variation of KIC 8840638 using high-precision time-series data from mission. The analysis reveals this target is a new Algol-type eclip…
An optical and X-ray study of the contact binary, BH Cassiopeiae
Junhui Liu, Ali Esamdin, Yu Zhang +10
We present the revised and high quality CCD time series observations in 2017 and 2018 of the W UMa-type contact binary BH~Cas. The combination of our new determinations of minimum…
