Rotational and pulsational variability in the TESS light curve of HD27463
V. Khalack, C. Lovekin, D. M. Bowman +8
The new photometric data on pulsating Ap star HD~27463 obtained recently with the Transiting Exoplanet Survey Satellite (\textit{TESS}) are analysed to search for variability. Our…
HD 42659: The only known roAp star in a spectroscopic binary observed with B photometry, TESS and SALT
Daniel L. Holdsworth, Hideyuki Saio, Donald W. Kurtz
We present a multi-instrument analysis of the rapidly oscillating Ap (roAp) star HD 42659. We have obtained photometric data for this star and use these data, in conjunction wi…
Adaptive elliptical aperture photometry: a software package for high-cadence ground-based photometry. I. Application to rapid oscillators observed from SAAO
Dominic M. Bowman, Daniel L. Holdsworth
Context. Modern space telescopes are currently providing high-precision light curves for a large fraction of the sky, such that many new variable stars are being discovered. Howeve…
Six new rapidly oscillating Ap stars in the Kepler long-cadence data using super-Nyquist asteroseismology
Daniel R. Hey, Daniel L. Holdsworth, Timothy R. Bedding +6
We perform a search for rapidly oscillating Ap stars in the Kepler long-cadence data, where true oscillations above the Nyquist limit of 283.21 μHz can be reliably distinguished fr…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
