The Stellar Abundances and Galactic Evolution Survey (SAGES). IV. Surface Gravity Estimation and Giant-Dwarf Separation with the DDO51 Filter
Qiqian Zhang, Zhou Fan, Gang Zhao +16
Reliable estimation of stellar surface gravity (log ) for a large sample is crucial for evaluating stellar evolution models and understanding galactic structure; However, it is…
Additional Evidence for the Existence of a Primordial Disk System
Shuai Xu, Haibo Yuan, Bowen Huang +7
The origin of very metal-poor (VMP; [Fe/H] ) stars on planar orbits has been the subject of great attention since their first discovery. However, prior to the release of…
Architecture of Tianyu Software: Relative Photometry as a Case Study
Yicheng Rui, Yifan Xuan, Shuyue Zheng +8
Tianyu telescope, an one-meter robotic optical survey instrument to be constructed in Lenghu, Qinghai, China, is designed for detecting transiting exoplanets, variable stars and tr…
Identification of BHB stars using Synthetic SkyMapper colors from Gaia XP spectra
Guozhen Hu, Yang Huang, Wenyuan Cui +9
Blue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic su…
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: White Paper
Henggeng Han, Yang Huang, Beichuan Wang +11
This paper outlines the scientific goals and observational strategies of the Mini-SiTian array. Mounted at Xinglong Observatory, the Mini-SiTian array consists of three 30 cm teles…
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…
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…
The Mini-SiTian Array: Prospects of Searching for Tidal Disruption Events
Bei-chuan Wang, Jun-jie Jin, Yu Zhang +14
We assess the detectability of tidal disruption events (TDEs) using mock observations from the Mini-SiTian array. We select 100 host galaxy samples from a simulated galaxy catalog…
