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…
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…
Evolution of Stellar Activity and Habitable zone: I. Ultraviolet Emission of Dwarfs in Open Clusters and Field Stars
Xue Li, Song Wang, Jun Ma +3
Near-ultraviolet (NUV) radiation from dwarf stars plays a critical role in shaping the habitability of planetary systems, yet its long-term evolution across different spectral type…
Revisiting the Li abundances of Stars with and without Detected Planets from the High Resolution Spectroscopy
Jinxiao Qin, Hong-Liang Yan, Wenyuan Cui +12
Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-h…

The Mini-SiTian Array: the mini-SiTian Realtime Image Processing pipeline (STRIP)
Hongrui Gu, Yang Huang, Yongkang Sun +10
This paper provides a comprehensive introduction to the Mini-SiTian Real-Time Image Processing pipeline (STRIP) and evaluates its operational performance. The STRIP pipeline is spe…
Impact of Spectral Resolution on S-index and Its Application to Spectroscopic Surveys
Henggeng Han, Song Wang, Xue Li +2
Utilizing the PHOENIX synthetic spectra, we investigated the impact of spectral resolution on the calculation of -indices. We found that for spectra with a resolution lower than…
"Frog-eyes" in Astronomy: Monitoring Binary Radial Velocity Variations Through A Pair of Narrow-Band Filters
Chuanjie Zheng, Yang Huang, Jifeng Liu +13
Spectroscopic observations are a crucial step in driving major discoveries in the era of time-domain surveys. However, the pace of current spectroscopic surveys is increasingly una…
