Study of slowly rotating CP stars observed with TESS
O. Kobzar, V. Khalack, D. Bohlender +10
Since the end of 2018, the Transiting Exoplanet Survey Satellite (TESS) provides high-quality space data on stellar photometry to the astronomical community. We present the results…
VeSElkA: Vertical Stratification of Element Abundances in CP stars
Viktor Khalack, Francis LeBlanc, Oleksandr Kobzar
A portion of the upper main-sequence stars, called chemically peculiar (CP) stars, show significant abundance anomalies mainly due to atomic diffusion of chemical elements within t…
Revealing the nature of HD63401
Pavlo Kashko, Viktor Khalack, Oleksandr Kobzar +2
HD~63401 is known magnetic chemically peculiar (mCP) star that shows a slow rotation and probably possesses a hydrodynamically stable stellar atmosphere. In the latter case the ato…
MOBSTER: Establishing a Picture of Magnetic Massive Stars as a Population
Alexandre David-Uraz, Coralie Neiner, James Sikora +12
Magnetic massive and intermediate-mass stars constitute a separate population whose properties are still not fully understood. Increasing the sample of known objects of this type w…
Magnetic OB[A] Stars with TESS: probing their Evolutionary and Rotational properties -- The MOBSTER Collaboration
A. David-Uraz, C. Neiner, J. Sikora +14
In this contribution, we present the MOBSTER Collaboration, a large community effort to leverage high-precision photometry from the Transiting Exoplanet Survey Satellite (\textit{T…
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…
