TESS observations of Be stars: a new interpretation
Luis A. Balona, Dogus Ozuyar
Light curves of 57 classical Be stars in TESS sectors 1 - 15 are examined. In most Be stars, the periodogram shows groups at a fundamental and one or more harmonics, which we attri…
Evidence for spots on hot stars suggests major revision of stellar physics
Luis A. Balona
It has long been thought that starspots are not present in the A and B stars because magnetic fields cannot be generated in stars with radiative envelopes. Space observations show…
New Beta Cephei stars with KELT
Jonathan Labadie-Bartz, Gerald Handler, Joshua Pepper +9
We present the results of a search for Galactic Beta Cephei stars, which are massive pulsating stars with both pressure modes and mixed modes. Thus, these stars can serve as benchm…
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…
Rotational modulation in TESS B stars
L. A. Balona, G. Handler, S. Chowdhury +6
Light curves and periodograms of 160 B stars observed by the TESS space mission and 29 main-sequence B stars from Kepler and K2 were used to classify the variability type. There ar…
