Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
The authors re‑examine the object G6096, previously thought to be a wide binary with a compact companion, and using spectroscopy, radial‑velocity and astrometric analysis together…
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…
