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…
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…
Varying core-envelope coupling efficiency identified from stellar rotation--activity relation
Henggeng Han, Song Wang, Huiqin Yang +5
Core-envelope coupling provides a reasonable explanation of the spin-down stalling of stars in open clusters, which was not predicted by classical gyrochronology. However, it remai…
Evolution of Stellar Activity and Habitable Zone II: Ca H&K Emissions of Late-type Dwarfs
Henggeng Han, Song Wang, Xue Li +3
Stellar chromospheric activity serves as a valuable proxy for estimating stellar ages, though its applicable range and accurate functional form are still debated. In this study, ut…
A Large and Precise All-Sky Photometric Standard Star Dataset Across More Than 200 Passbands
Kai Xiao, Yang Huang, Haibo Yuan +12
High-precision photometric standard stars play a key role in enabling accurate photometric calibration and advancing various fields of astronomy. However, due to limitations in cal…
Evaluating the chromospheric structure model of AD Leo using RH1.5D and magnetic field data
Shuai Liu, Jianrong Shi, Huigang Wei +4
Context. The interplay between surface magnetic topology and chromospheric heating in active M dwarfs remains poorly constrained, limiting our understanding of their magnetic cycle…
