Asteroseismology of the High-amplitude Scuti Star EH Librae
Xiran Xie, Jianning Fu, Gang Meng +7
A subclass of intermediate mass variables Scuti stars, known as High-amplitude Scuti (HADS) stars, exhibits pronounced radial pulsations. We used ground- and space-based ob…
Pulsation Properties of Blazhko and Non-Blazhko RRab Stars
Peng Zong, Jian-Ning Fu, Jie Su +8
In this study, we conduct a comparative analysis of the properties of Blazhko and non-Blazhko RRab stars. We identified 1054 non-Blazhko and 785 Blazhko RRab stars in the photometr…
Asteroseismological analysis of the non-Blazhko RRab star EPIC~248846335 in LAMOST -- Kepler K2 project
Peng Zong, Jian-Ning Fu, Jie Su +9
We conduct an asteroseismological analysis on the non-Blazhko ab-type RR Lyrae star EPIC 248846335 employing the Radial Stellar Pulsations (RSP) module of the Modules for Experimen…
Two high-amplitude Scuti- Doradus hybrids constrained by the radial fundamental p and equally spaced g modes
Xinghao Chen, Xiaobin Zhang, Yan Li +1
Based on 2-minute cadence TESS data, we investigate pulsations of TIC 65138566 and TIC 139729335 and discover them to be two new HADS stars with equally spaced g modes. We recogniz…
