Seismic test of the mass-radius relationship of hydrogen-atmospheric white dwarf stars
Tianqi Cang, Jiayi Zhang, Jian-Ning Fu +2
The pulsation of white dwarfs provides crucial information on stellar parameters for understanding the atmosphere and interior structure of these stars. In this study, we present a…

Distinguishing super-Nyquist frequencies via their temporal variation in Doradus stars from continuous photometry
Xuan Wang, Weikai Zong, Xiao-Yu Ma +3
As mixed with real pulsations, the reflection of super-Nyquist frequencies (SNFs) pose a threat to asteroseismic properties. Although SNFs have been studied in several pulsating st…

TIC441725813: A new bright hybrid sdB pulsator with differential core/envelope rotation
Wenchao Su, Stéphane Charpinet, Marilyn Latour +3
We present the detailed analysis of a new hybrid (p- and g-mode) sdB pulsator, TIC441725813 (TYC 4427-1021-1), discovered and monitored by TESS over 670 days. The TESS light curves…
