Decoding RR Lyrae light curves with deep learning for accurate absolute magnitude estimation
Shunxuan He, Huiwen Wu, Yang Huang +6
RR Lyrae stars are essential standard candles for distance measurements in the Milky Way and nearby galaxies. Traditional estimates rely on the Period--Absolute Magnitude--Metallic…
Differential Reddening and Extinction Law Analyses of Galactic Open Clusters
Xiaohan Chen, Shu Wang, Xiaodian Chen
Extinction significantly affects open cluster parameters and their use in studies of Galactic structure, yet homogeneous large sample measurements of open cluster extinction proper…
Correlation between the two-armed spiral in the -- plane and moving groups
Yan Xu, Chao Liu, Chengdong Li +5
We use a cross-matched sample of 3.7 million stars from Gaia DR3 and LAMOST DR7 to investigate the velocity substructures in the Milky Way disk. The median radial velocity as…
Surface brightness-color relations for red giant branch stars: Observational constraints on metallicity effects using the ARD method
Jianping Xiong, Xiaodian Chen, Jiao Li +5
Aims: We aim to quantify the metallicity dependence of the SBCR for red giant branch (RGB) stars and to test the robustness of the relation using asteroseismic radii, Gaia distance…
A Search for Variability of Ultracool Dwarfs with the Zwicky Transient Facility
Haomiao Huang, Shu Wang, Xiaodian Chen +2
Rotationally modulated photometric variability of ultracool dwarfs encodes key information about cloud structure and temperature contrasts. Large homogeneous optical datasets are c…
The Phenomenological Classification of TESS Eclipsing Binaries
Shi-Qi Liu, Kai Li, Xiao-Dian Chen +1
Eclipsing binaries are crucial astrophysical laboratories for studying stellar parameters and evolutionary processes. In this study, we constructed a machine-learning-based model f…
StarCLR: Contrastive Learning Representation for Astronomical Light Curves
Junyao Ding, Xiaodian Chen, Xinyi Gao +7
With the rapid development of time-domain surveys, the availability of massive light curve data offers new opportunities for studying stellar evolution and variable star classifica…
SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA): Atmospheric and Fundamental Parameters of Ultracool Dwarfs
Zhijun Tu, Shu Wang, Haomiao Huang +2
We present the SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA), a homogeneous sample of 1675 field ultracool dwarfs with continuous 0.75--5~m spectrophotometry from SPHE…
