Massive open star clusters using the VVV survey II. Discovery of six clusters with Wolf-Rayet stars
A. -N. Chené, J. Borissova, C. Bonatto +20
Context: The ESO Public Survey "VISTA Variables in the Vía Láctea" (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge,…
The 2.35 year itch of Cyg OB2 #9 - I. Optical and X-ray monitoring
Y. Naze, L. Mahy, Y. Damerdji +5
Context: Nonthermal radio emission in massive stars is expected to arise in wind-wind collisions occurring inside a binary system. One such case, the O-type star Cyg OB2 #9, was pr…
9 Sgr: uncovering an O-type spectroscopic binary with an 8.6 year period
G. Rauw, H. Sana, M. Spano +4
The O-type object 9 Sgr is a well-known synchrotron radio emitter. This feature is usually attributed to colliding-wind binary systems, but 9 Sgr was long considered a single star.…
Evidence for a physically bound third component in HD 150136
L. Mahy, E. Gosset, H. Sana +4
Context. HD150136 is one of the nearest systems harbouring an O3 star. Although this system was for a long time considered as binary, more recent investigations have suggested the…
