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 …
WR 148: Identifying the companion of an extreme runaway massive binary
Melissa Munoz, Anthony F. J. Moffat, Grant M. Hill +5
WR 148 (HD 197406) is an extreme runaway system considered to be a potential candidate for a short-period (4.3173 d) rare WR + compact object binary. Provided with new high resolut…
The BRITE Constellation nanosatellite mission: Testing, commissioning and operations
H. Pablo, G. N. Whittaker, A. Popowicz +27
BRITE (BRIght Target Explorer) Constellation, the first nanosatellite mission applied to astrophysical research, is a collaboration among Austria, Canada and Poland. The fleet of s…
The CHARA Array resolves the long-period Wolf-Rayet binaries WR 137 and WR 138
Noel D. Richardson, Tomer Shenar, Olivier Roy-Loubier +10
We report on interferometric observations with the CHARA Array of two classical Wolf-Rayet stars in suspected binary systems, namely WR 137 and WR 138. In both cases, we resolve th…
An extensive spectroscopic time-series of three Wolf-Rayet stars. I. The lifetime of large-scale structures in the wind of WR 134
E. J. Aldoretta, N. St-Louis, N. D. Richardson +46
During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been analyzed for WR 134…
Massive pulsating stars observed by BRITE-Constellation. I. The triple system Beta Centauri (Agena)
A. Pigulski, H. Cugier, A. Popowicz +16
This paper aims to precisely determine the masses and detect pulsation modes in the two massive components of Beta Cen with BRITE-Constellation photometry. In addition, seismic mod…
The roAp star Circini as seen by BRITE-Constellation
W. W. Weiss, H. -E. Fröhlich, A. Pigulski +25
We report on an analysis of high-precision, multi-colour photometric observations of the rapidly-oscillating Ap (roAp) star Cir. These observations were obtained with the BRITE…
