Evolving pulsation of the slowly rotating magnetic beta Cep star xi 1 CMa
Sean B. Begy, Gregg A. Wade, Gerald Handler +3
We report BRITE-Constellation photometry of the beta Cep pulsator xi 1 CMa. Analysis of these data reveals a single pulsation period of 0.2095781(3) d, along with its first and sec…
Rotationally modulated photometric variations in B supergiants?
Alexandre David-Uraz, Gregg Wade, Anthony Moffat +3
In this contribution, we present BRITE observations of the early-B supergiants Ori and Ori. We perform a preliminary analysis of the data acquired over the first two Orion…
Constraining the near-core rotation of the gamma Doradus star 43 Cygni using BRITE-Constellation data
Konstanze Zwintz, Timothy Van Reeth, Andrew Tkachenko +8
Photometric time series of the Dor star 43 Cyg obtained with the BRITE-Constellation nano-satellites allow us to study its pulsational properties in detail and to constrain its…
The variability of the BRITE-est Wolf-Rayet binary, Velorum I. Photometric and spectroscopic evidence for colliding winds
Noel D. Richardson, Christopher M. P. Russell, Lucas St-Jean +26
We report on the first multi-color precision light curve of the bright Wolf-Rayet binary Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation…
BRITE-Constellation: Data processing and photometry
Adam Popowicz, Andrzej Pigulski, Krzysztof Bernacki +15
The BRITE mission is a pioneering space project aimed at the long-term photometric monitoring of the brightest stars in the sky by means of a constellation of nano-satellites. Its…
The MOST view of Cepheids
L. Molnár, A. Derekas, R. Szabó +6
The MOST space telescope observed four Cepheid variables so far, all of different subtypes. Here we summarize the results obtained and the possible ways to continue to study these…
