Unresolved triple systems in the aged open cluster Trumpler 19: Discovery, confirmation, and implications
D. Minniti, R. K. Saito, V. D. Ivanov +31
It is difficult to identify unresolved triple and higher-order systems beyond the solar vicinity. Star clusters yield controlled environments with known physical parameters, provid…
Analysis of physical processes in eruptive YSOs with near infrared spectra and multi-wavelength light curves
Zhen Guo, P. W. Lucas, C. Contreras Peña +11
The decade-long Vista Variables in the Via Lactea (VVV) survey has detected numerous highly variable young stellar objects (YSOs). We present a study of 61 highly variable VVV YSOs…
Conditions in the WR 140 wind-collision region revealed by the 1.083-micron He I line profile
Peredur M. Williams, Watson P. Varricatt, André-Nicolas Chené +10
We present spectroscopy of the P~Cygni profile of the 1.083-micron He I line in the WC7 + O5 colliding-wind binary (CWB) WR 140 (HD 193793), observed in 2008, before its periastron…
Clumping in the Winds of Wolf-Rayet Stars
André-Nicolas Chené, Nicole St-Louis, Anthony F. J. Moffat +1
We attempt to determine the driver for clumping in hot-star winds by extending the measure of the spectral variability level of Galactic Wolf-Rayet stars to by far the hottest know…
Massive stars in the young cluster VVV CL074
F. Martins, A. N. Chené, J. -C. Bouret +4
We obtained K-band spectroscopy of the brightest members of the cluster VVV CL074 in order to identify the massive star population. We also determined the stellar properties of the…
Investigating the origin of the spectral line profiles of the Hot Wolf-Rayet Star WR2
A. -N. Chené, N. St-Louis, A. F. J. Moffat +12
The hot WN star WR2 (HD6327) has been claimed to have many singular characteristics. To explain its unusually rounded and relatively weak emission line profiles, it has been propos…
