Six β Cephei stars as seen with BRITE and from the ground

G. Handler and the BRITE Team

We present an overview of BRITE-Constellation observations of β Cephei stars that have been assigned to the first author as contact PI. We discuss the objects individually, show the synergies with ground-based observations, possible problems in the analysis and confront the quality of the results between the two types of observing method. In comparison to ground-based photometry, BRITE measurements result in lower noise levels in the periodogram. We note that due to longer integration times possible for some satellites, BRITE can now obtain much better results for fainter stars than previously. In addition, thanks to its better low-frequency stability, BRITE provides evidence that gravity mode pulsation is more common among β Cephei stars than previously thought.
