Expanding stellar horizons with polarized light
J. Vandersnickt, R. Ochoa Armenta, V. Vanlaer +16
The polarization of light is a critically under-utilized, rich source of information in astronomy. For stars in particular, surface magnetism polarization that can be detected and…
TESS Cycle 2 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46
We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
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…
MOBSTER -- VI. The crucial influence of rotation on the radio magnetospheres of hot stars
M. E. Shultz, S. P. Owocki, A. ud-Doula +13
Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current sheet f…
TESS survey of rotational and pulsational variability of mercury-manganese stars
O. Kochukhov, V. Khalack, O. Kobzar +4
Mercury-manganese (HgMn) stars are late-B upper main sequence chemically peculiar stars distinguished by large overabundances of heavy elements, slow rotation, and frequent members…
