WR20a: a massive cornerstone binary system comprising two extreme early-type stars
G. Rauw, M. De Becker, Y. Naze +6
We analyse spectroscopic observations of WR20a revealing that this star is a massive early-type binary system with a most probable orbital period of \sim 3.675 days. Our spectra in…

Near IR Spectroscopic monitoring of WR 140 during the 2001 periastron passage
W. P. Varricatt, P. M. Williams, N. M. Ashok
We present new spectra of WR 140 (HD 193793) in the JHK bands with some covering the 1.083-micron He I emission line at higher resolution, observed between 2000 October and 2003 Ma…

Radio emission models of Colliding-Wind Binary Systems
S. M. Dougherty, J. M. Pittard, L. Kasian +3
We present calculations of the spatial and spectral distribution of the radio emission from a wide WR+OB colliding-wind binary system based on high-resolution hydrodynamical simula…
