HD 213258: a new rapidly oscillating, super-slowly rotating, strongly magnetic Ap star in a spectroscopic binary
Gautier Mathys, Viktor Khalack, Oleksandr Kobzar +2
We report about HD 213258, an Ap star that we recently identified as presenting a unique combination of rare, remarkable properties. Our study of this star is based on ESPaDOnS Sto…
Analysis of eight magnetic chemically peculiar stars with rotational modulation
O. Kobzar, V. Khalack, D. Bohlender +9
Since the end of 2018, the Transiting Exoplanet Survey Satellite (TESS) has provided stellar photometry to the astronomical community. We have used TESS data to study rotational mo…
Long-period Ap stars discovered with TESS data: The northern ecliptic hemisphere
G. Mathys, D. W. Kurtz, D. L. Holdsworth
The rotation periods of the magnetic Ap stars span five to six orders of magnitude. Period differentiation must have taken place at the pre-main sequence stage, but the physical pr…
