LTD064402+245919, compact binary or subgiant with red star eclipsing binary?
Jincheng Guo, Cheng Liu
Recently, a single-line spectroscopic binary, LTD064402+245919, has been discovered by Yang et al. Using data from LAMOST and ZTF, the unseen companion is estimated to have a mass…
GD424 -- a helium-atmosphere white dwarf with a large amount of trace hydrogen in the process of digesting a rocky planetesimal
Paula Izquierdo, Odette Toloza, Boris T. Gänsicke +5
The photospheric metal pollution of white dwarfs is now well-established as the signature of the accretion of planetary debris. However, the origin of the trace hydrogen detected i…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
A New Luminous blue variable in the outskirt of the Andromeda Galaxy
Yang Huang, Huaiwei Zhang, Chun Wang +8
The hot massive luminous blue variables (LBVs) represent an important evolutionary phase of massive stars. Here, we report the discovery of a new LBV -- LAMOST J0037+4016 in the di…
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…
A Combined Chandra and LAMOST Study of Stellar Activity
Lin He, Song Wang, Jifeng Liu +5
We probed stellar X-ray activity over a wide range of stellar parameters, using {\it Chandra} and LAMOST data. We measured the X-ray-to-bolometric luminosity ratio ($R_X = L_X/L_{\…
