BRITE-Constellation high-precision time-dependent photometry of the early-O-type supergiant Puppis unveils the photospheric drivers of its small- and large-scale wind structures
Tahina Ramiaramanantsoa, Anthony F. J. Moffat, Robert Harmon +33
From months of dual-band optical photometric monitoring at the mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star …
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…
To and beyond! The He I absorption variability across the 2014.6 periastron passage of Carinae
Noel D. Richardson, Thomas I. Madura, Lucas St-Jean +11
We have monitored the massive binary star Carinae with the CTIO/SMARTS 1.5~m telescope and CHIRON spectrograph from the previous apastron passage of the system through the rece…
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…
He II 4686 emission from the massive binary system in Car: constraints to the orbital elements and the nature of the periodic minima
M. Teodoro, A. Damineli, B. Heathcote +27
η Carinae is an extremely massive binary system in which rapid spectrum variations occur near periastron. Most notably, near periastron the He II line increases rapidly in…
