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…
Classification for 969 double-mode RR Lyrae stars from Zwicky Transient Facility
Jianxing Zhang, Xiaodian Chen, Shu Wang +2
RR Lyrae (RRL) variable stars are cornerstone distance indicators. In particular, double-mode RR Lyrae (RRd) stars enable period--luminosity relations (PLRs) that are less sensitiv…
A Large Sample of JWST/NIRSpec Brown Dwarfs: New Distant Discoveries
Zhijun Tu, Shu Wang, Xiaodian Chen +1
Brown dwarfs are essential probes of stellar and planetary formation, yet their low luminosities pose challenges for detection at large Galactic distances. The James Webb Space Tel…
A Detailed Analysis of the Milky Way Warp Based on Classical Cepheids
Xiaoyue Zhou, Xiaodian Chen, Licai Deng +3
Classical Cepheids (CCs) are important probes for the large-scale warp structure of the Milky Way. Using Gaia DR3 CCs, we establish an optimal time-dependent warp model, where the…
A search of periodic variable stars in the LMC by JWST photometry
Jiyu Wang, Xiaodian Chen, Jianxing Zhang +3
Based on high-resolution near-infrared photometric data from the James Webb Space Telescope (JWST) targeting the Large Magellanic Cloud (LMC), this study attempts to evaluate the f…
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…
The Tip of Red Giant Branch Distances to Nearby Dwarf Galaxies WLM and Sextans A with JWST
Ziming Yan, Shu Wang, Xiaodian Chen +1
Distance measurements to extragalactic systems that are both accurate and precise are cornerstones of modern astrophysics, underpinning the calibration of standard candles and the…
A 0.3\% calibration of the W UMa-type contact binary luminosity based on Gaia DR3
Jing Li, Xiaodian Chen, Shu Wang +3
W Ursa Majoris (W UMa)-type contact binary systems (CBs) with period--luminosity (PL) relations are valuable distance indicators. The PL relations of CBs are affected by metallicit…
Period--Luminosity Relations for Double-mode Sct Stars
Qi Jia, Xiaodian Chen, Shu Wang +3
Previous studies of the Period--Luminosity relations (PLRs) of Delta Scuti ( Sct) stars have focused on those with a single pulsation mode. However, for Sct stars with many…
