Statistical evidence for linear combination frequencies in γ Doradus stars being nonlinear resonant modes

Yanqi Mo, Weikai Zong, Xuan Wang +4

The quest for the origin of linear combination frequencies in pulsating stars is critical for mode identification and subsequent seismic modeling. Hybrid γ Doradus (Dor) stars prov…

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…

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…

Variable white dwarfs in TMTS: Asteroseismological analysis of a ZZ Ceti star, TMTS J17184064+2524314

Jincheng Guo, Yanhui Chen, Yonghui Yang +24

The Tsinghua University-Ma Huateng Telescope for Survey (TMTS) has been constantly monitoring the northern sky since 2020 in search of rapidly variable stars. To find variable whit…

Amplitude and frequency variations in PG~0101+039 from K2 photometry -- A pulsating hot B subdwarf star in an unsynchronized binary system

Xiao-Yu Ma, Weikai Zong, Jian-Ning Fu +3

K2 photometry is suitable for the exploitation of mode variability on short timescales in hot B subdwarf stars, which is important to constrain nonlinear quantities addressed by th…
