Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…
Characterizing Orbital Parameters of Hot Subdwarf Binaries with Multiple Spectroscopic Surveys
XInlin Zhao, Song Wang, Zhenxin Lei +5
Hot subdwarfs (HSDs) provide critical insights into the physical mechanisms governing binary evolution. In this work, we conduct a systematic analysis of 157 HSDs, selected from Ga…
Nature of HD 251108: an RS CVn binary with a long-term evolving spot
Xinlin Zhao, Song Wang, B. Fuhrmeister +5
Recently, the Lobster Eye Imager for Astronomy (LEIA) detected the longest-lasting and most energetic stellar X-ray flare event from HD 251108. In this work, we re-determined the a…
Retarded Stellar Dynamo in Tidally Deformed M Dwarfs
Song Wang, Wenbo Li, Henggeng Han +3
Current studies of stellar dynamos primarily focus on spherical stars, leaving their behavior in distorted stars largely unexplored. We utilize stars of varying distortions to exam…
A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Qian-Yu An, Yang Huang, Wei-Min Gu +21
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitatio…
The Mini-SiTian Array: first-two-year operation
Min He, Hong Wu, Liang Ge +70
The SiTian project, designed to utilize 60 telescopes distributed across multiple sites in China, is a next-generation time-domain survey initiative. As a pathfinder for the SiTian…
Searching for accreting compact binary systems from spectroscopy and photometry: Application to LAMOST spectra
Xinlin Zhao, Song Wang, Jifeng Liu
Compact objects undergoing mass transfer exhibit significant (and double-peaked) emission lines. Recently, new methods have been developed to identify black hole X-ray binari…
A massive white dwarf or low-mass neutron star discovered by LAMOST
Xinlin Zhao, Song Wang, Pengfei Wang +3
We report the discovery of a close binary J0606+2132 (Gaia DR3 3423365496448406272) with days containing a possible massive white dwarf or a neutron star using t…
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 Multi-station Meteor Monitoring (M) System. I. Design and Testing
Z. Li, H. Zou, J. Liu +8
Meteors carry important and indispensable information about the interplanetary environment, which can be used to understand the origin and evolution of our solar system. We have de…
A potential mass-gap black hole in a wide binary with a circular orbit
Wang Song, Zhao Xinlin, Feng Fabo +28
Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised t…
Stellar cycle and evolution of polar spots in an M+WD binary
Xinlin Zhao, Song Wang, Xue Li +4
Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total…
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.…
Binaries with possible compact components discovered from the LAMOST Time-Domain Survey of four 2 plates
Li Xue, Wang Song, Zhao Xinlin +4
Time-domain (TD) spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) can provide accurate and high-cadence radial velocities (RVs). In th…
