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…
An improved asteroseismic age of the rapid rotator Altair from TESS data
Michel Rieutord, Daniel R. Reese, Joey S. G. Mombarg +1
Understanding the effects of rotation in stellar evolution is key to modelling early-type stars, half of which have equatorial velocities over 100 km/s. The nearby star Altair is a…
Short-period pulsating hot-subdwarf stars observed by TESS II. Northern ecliptic hemisphere
A. S. Baran, S. Charpinet, R. H. Østensen +5
We present results of a continuation of our Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects observed during Years 2 and 4…
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…
