Ema Šipková, Alex Kemp, Dario Fritzewski +4
Space-based photometry has substantially increased the number of pulsating stars found in binary systems by more than four orders of magnitude. Combined with high-resolution spectr…
Probing stellar rotation in the Pleiades with gravity-mode pulsators
D. J. Fritzewski, A. Kemp, G. Li +1
Due to their proximity, the Pleiades are an important benchmark open cluster. Despite its status, asteroseismic analyses of its members are rare. In particular, the gravity-mode (g…
Automated all-sky detection of γ Doradus / δ Scuti hybrids in TESS data from positive unlabelled (PU) learning
Mykyta Kliapets, Pablo Huijse, Andrew Tkachenko +4
The Transiting Exoplanet Survey Satellite (TESS) mission has observed hundreds of millions of stars, substantially contributing to the available pool of high-precision photometric…
Stationary quasi-periodic pulsations in 20-second cadence TESS flares
Aadish Joshi, Tom Van Doorsselaere, Daye Lim +1
Context. Quasi-periodic pulsations (QPPs) are an inherent feature of solar and stellar flares. However, the mechanism behind them is debated hence it is necessary to further study…
