Photometric differences between modulated and non-Blazhko RRab Lyrae stars in the Galactic bulge
M. Skarka, Z. Prudil
We present our results of searching for differences in light curves of modulated and non-modulated RRab stars in the Galactic bulge. We examined a sample of more than 8000 stars. T…
On the interpretation of the long-term cyclic period variations in RR Lyrae stars
M. Skarka, J. Liška, Á. Sódor +4
Many RR Lyrae stars show long-term variations of their pulsation period, some of them in a cyclic way. Such behaviour can be attributed to the light-travel time effect (LTTE) cause…
K2 Photometry of RR Lyrae Stars
E. Plachy, L. Molnár, A. Bódi +5
Thousands of RR Lyrae stars have been observed by the \textit{Kepler} space telescope so far. We developed a photometric pipeline tailored to the light variations of these stars, c…
The search for roAp stars: null results and new candidates from Stroemgren-Crawford photometry
E. Paunzen, G. Handler, K. Honkova +10
The rapidly oscillating Ap (roAp) stars exhibit pulsational photometric and/or radial velocity variations on time scales of several minutes, which are essential to test current pul…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
