Photometric and spectroscopic variability of 53 Per
E. Niemczura, A. Pigulski, H. Lehmann +4
A new investigation of the variability of the SPB-type star 53 Per is presented. The analysis of the BRITE photometry allowed us to determine eight independent frequencies and the…
The solitary g-mode frequencies in early B-type stars
J. Daszynska-Daszkiewicz, P. Walczak, A. A. Pamyatnykh +2
We present possible explanations of pulsations in early B-type main sequence stars which arise purely from the excitation of gravity modes. There are three stars with this type of…
BRITE photometry of seven B-type stars
Ernst Paunzen, Monika Rode-Paunzen
We present the time series analysis of seven B-type stars (HD 121790, HD 122980, HD 129116, HD 133242, HD 144294, HD 145482, and HD 145502) observed with the BRITE satellites. Furt…
A BRITE view on delta Scuti and gamma Doradus stars
Konstanze Zwintz, the BRITE-Constellation Executive Science Team
BRITE-Constellation has obtained data for a few delta Scuti and gamma Doradus type stars. A short overview of the pulsational content found in five stars - beta Cassiopeiae, epsilo…
Understanding the photometric variability of ζ Ori Aa
B. Buysschaert, C. Neiner, T. Ramiaramanantsoa +3
We studied the variability of the magnetic O-type supergiant Ori Aa using multi-colour BRITE photometry. We confirmed the known rotation frequency …
