Are Hot Jupiters Tidally Disrupted During Stellar Main Sequence?
Qingru Hu, Wei Zhu, Yang Huang +1
Once hot Jupiters (HJs) reach their very close orbits, they are expected to experience orbital decay due to tidal interactions with their host star. However, the strength of tidal…
Filter Design for Estimating the Stellar Metallicity of Metal-poor Stars from Gaia XP Spectra
Ruifeng Shi, Yang Huang, Kai Xiao +5
The estimation of stellar atmospheric parameters for large-scale samples, particularly metal-poor stars, is a cornerstone of Galactic archaeology. In this work, we optimized a phot…
The solar-like latitudinal distribution of flaring activities revealed by TESS, APOGEE and GALAH
Huiqin Yang, Shuai Liu, Yang Huang +2
Flare flux reflect contribution from active regions rather than the whole hemisphere of a star. Unlike the amplitude of light-curves caused by starspots, the flare detection is ind…
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…
"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…
