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…

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 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…

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…

The rotation properties of Sct and Dor stars

Jiyu Wang, Xiaodian Chen, Licai Deng +2

Based on the LAMOST spectroscopy and TESS time-series photometry, we have obtained a main-sequence star sample of Scuti and Doradus stars. The sample includes 1534 Sct…

Multi-mode delta Sct stars from the Zwicky Transient Facility Survey

Qi Jia, Xiaodian Chen, Shu Wang +3

We obtain the largest catalog of multi-mode Sct stars in the northern sky to date using the Zwicky Transient Facility (ZTF) Data Release 20 (DR20). The catalog includes 2254 ob…

Possible evidence of hydrogen emission in the first-overtone and multi-mode RR Lyrae variables

Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4

The nature of shock waves in non-fundamental mode RR Lyrae stars remains a mystery because of limited spectroscopic observations. We apply a pattern recognition algorithm on spectr…
