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…
The Mini-SiTian Array: Imaging Processing Pipeline
Kai Xiao, Zhirui Li, Yang Huang +19
As a pathfinder of the SiTian project, the Mini-SiTian (MST) array, employed three commercial CMOS cameras, represents a next-generation, cost-effective optical time-domain survey…
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…
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…
Calibration of Complementary Metal-oxide-semiconductor Sensor-based Photometry to a Few-millimagnitude Precision: The Case of the Mini-SiTian Array
Kai Xiao, Yang Huang, Haibo Yuan +14
We present a pioneering achievement in the high-precision photometric calibration of CMOS-based photometry, by application of the Gaia BP/RP (XP) spectra-based synthetic photometry…
"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…
