Chemically peculiar stars investigated by the BRITE Mission
Teja Begari, Klaus Bernhard, Ernst Paunzen +1
We present a comprehensive analysis of BRITE photometry for 85 chemically peculiar stars, aimed at refining or determining their rotational periods. Utilizing a uniform Lomb-Scargl…

GALEX UV survey of magnetic chemically peculiar stars in the Kepler prime field
Emanuele Bertone, Stefan Hümmerich, Miguel Chávez +8
Magnetic chemically peculiar (mCP) stars are strongly magnetic upper main-sequence stars that exhibit light rotational variability due to an uneven surface distribution of certain…

A new sample of super-slowly rotating Ap (ssrAp) stars from the Zwicky Transient Facility survey
S. Hümmerich, K. Bernhard, E. Paunzen
The magnetic chemically peculiar Ap stars exhibit an extreme spread of rotational velocities, the reason of which is not well understood. Ap stars with rotational periods of 50 day…
