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…
CG X-1: an eclipsing Wolf-Rayet ULX in the Circinus galaxy
Yanli Qiu, Roberto Soria, Song Wang +7
We investigated the time-variability and spectral properties of the eclipsing X-ray source Circinus Galaxy X-1 (GG X-1), using Chandra, XMM-Newton and ROSAT. We phase-connected the…
X-ray Activity from Different Types of Stars
Lin He, Song Wang, Xiaojie Xu +10
X-ray emission is an important indicator of stellar activity. In this paper, we study stellar X-ray activity using the XMM-Newton and LAMOST data for different types of stars. We p…
