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…
A Search for High Frequency Oscillations in TESS Cycle 7
Guanda Huang, Xiaodian Chen, Shu Wang +2
High-quality, short-cadence photometry from TESS enables the detection of rapid oscillators with unprecedented sensitivity. In this work, we conduct a homogeneous search for high-f…
The extinction distances for over a thousand planetary nebulae with Gaia measurements
Juan Deng, Shu Wang, Biwei Jiang +1
Although Gaia has identified the central stars of planetary nebulae (CSPNe) for about 70% of known Galactic planetary nebulae (PNe), reliable distance estimates remain incomplete,…
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 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…
