TESS Observations of Stochastic Low-frequency Variability in Extreme Helium Stars
Courtney L. Crawford, C. Simon Jeffery, May G. Pedersen +4
Extreme helium stars (EHes) are low-mass hydrogen-deficient stars thought to be the products of double white dwarf mergers. Despite prolonged ground-based observations, there is no…
Halo Photometry and Asteroseismology for 98 of the Brightest Stars Observed by TESS
Jonatan Rudrasingam, Timothy R. Bedding, Benjamin J. S. Pope +4
The Transiting Exoplanet Survey Satellite (TESS) mission has facilitated studies of asteroseismology, eclipsing binaries, and transits in many stars. However, the brightest stars s…
Testing Red Clump Models with the Asteroseismic Binary KIC 10841730
Lea S. Schimak, Timothy R. Bedding, Courtney L. Crawford +9
Binaries in which both stars are pulsating are rare but extremely valuable. We present the first study of an asteroseismic binary system consisting of a core helium-burning red clu…
Stochastic low-frequency variability of 50 massive stars in the Cygnus OB associations and the Small Magellanic Cloud
M. G. Pedersen, L. Bildsten
In recent years, high-precision high-cadence space photometry has revealed that stochastic low frequency (SLF) variability is common in the light curves of massive stars. We use th…
Testing the wavelength dependence of oscillations and granulation in red giants using Kepler and TESS
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
Stellar oscillations and granulation in red giants are both powered by convection. Studying the wavelength dependence of their amplitudes can provide useful insights on the driving…
Modelling Hydrogen-deficient Carbon stars in MESA -- The effects of total mass and mass ratio
Courtney L. Crawford, Nikita Nikultsev, Geoffrey C. Clayton +3
Hydrogen-deficient Carbon (HdC) stars are rare, low-mass, chemically peculiar, supergiant variables believed to be formed by a double white dwarf (DWD) merger, specifically of a Ca…
Identifying 850 delta Scuti pulsators in a narrow Gaia colour range with TESS 10-minute full-frame images
Amelie K. Read, Timothy R. Bedding, Prasad Mani +7
We use TESS 10-minute Full Frame Images (Sectors 27-55) to study a sample of 1708 stars within 500 pc of the Sun that lie in a narrow colour range in the centre of the delta Scuti…
