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…
Photometric activity cycles in fast-rotating stars: Revisiting the reality of stellar activity cycle branches
Deepak Chahal, Devika Kamath, Richard de Grijs +2
We aim to detect activity cycles in young main-sequence stars, analogous to the 11-year solar cycle, using combined photometric survey data. This research will enhance our understa…
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…
