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…

The Dependence of the Extinction Coefficient on Reddening for Galactic Cepheids

Huajian Wang, Xiaodian Chen, Shu Wang

Cepheids are fundamental distance indicators, playing a crucial role not only in the cosmic distance ladder but also in mapping the structure, kinematics, and extinction properties…

Distances of Supernova Remnants Associated with Neutron Stars in the Galaxy

Xiaohan Chen, Shu Wang, Xiaodian Chen

Accurate distance measurements to supernova remnants (SNRs) are essential for determining their physical parameters, such as size, age, explosion energy, and for constraining the p…

Milky Way Classical Cepheids Distances from Calibrated Infrared Period-Luminosity-Metallicity Relations

Huajian Wang, Xiaodian Chen

Classical Cepheids (DCEPs) serve as fundamental standard candles for measuring cosmic distances and investigating the structure and evolution of the Milky Way disc. However, accura…
