Stellar X-ray activity across the Hertzsprung-Russell diagram. I. Catalogs

Song Wang, Yu Bai, Lin He +1

Stellar magnetic activity provides substantial information on the magnetic dynamo and the coronal heating process. We present a catalog of X-ray activity for about 6000 stars, base…

A Catalog of Short Period Spectroscopic and Eclipsing Binaries Identified from the LAMOST & PTF Surveys

Fan Yang, Richard J. Long, Su-Su Shan +7

Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information, taking…

Phase-dependent study of near-infrared disk emission lines in LB-1

Jifeng Liu, Zheng Zheng, Roberto Soria +19

The mass, origin and evolutionary stage of the binary system LB-1 has been the subject of intense debate, following the claim that it hosts an 70 black hole, in st…

A wide star-black-hole binary system from radial-velocity measurements

Jifeng Liu, Haotong Zhang, Andrew W. Howard +52

All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…

Searching for Black Hole Candidates by LAMOST and ASAS-SN

Ling-Lin Zheng, Wei-Min Gu, Tuan Yi +13

Most dynamically confirmed stellar-mass black holes and the candidates were originally selected from X-ray outbursts. In the present work, we search for black hole candidates in th…

Long rotation period main-sequence stars from Kepler SAP light curves

Kaiming Cui, Jifeng Liu, Shuhong Yang +7

Stellar rotation plays a key role in stellar activity. The rotation period could be detected through light curve variations caused by starspots. Kepler provides two types of light…
