Identification and characterization of 15265 super-Nyquist frequencies in 1309 δ Scuti stars from Kepler photometry

Yanqi Mo, Weikai Zong, Xuan Wang +5

The frequency of pressure (p) mode in ~Scuti stars can exceed the Nyquist limit of \textit{Kepler} long-cadence photometry. {These 'super-Nyquist frequencies' (SNFs) are observe…

A new code for low-resolution spectral identification of white dwarf binary candidates

Genghao Liu, Baitian Tang, Liangliang Ren +7

Close white dwarf binaries (CWDBs) are considered to be progenitors of several exotic astronomical phenomena (e.g., type Ia supernovae, cataclysmic variables). These violent events…

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…

Stellar atmospheric parameters of 11,000 RR Lyrae stars from LAMOST Spectra

Jiangtao Wang, Jianrong Shi, Jianning Fu +2

Accurate determination of the stellar atmospheric parameters of RR Lyrae stars (RRLs) requires short individual exposures of the spectra to mitigate pulsation effects. We present i…

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…

Flares hunting in hot subdwarf and white dwarf stars from Cycles 1-5 of TESS photometry

Keyu Xing, Weikai Zong, Roberto Silvotti +9

Stellar flares are critical phenomena on stellar surfaces, which are closely tied to stellar magnetism. While extensively studied in main-sequence (MS) stars, their occurrence in e…
