The 2.35 year itch of Cyg OB2 #9. II. Radio monitoring
R. Blomme, Y. Naze, D. Volpi +5
Cyg OB2 #9 is one of a small set of non-thermal radio emitting massive O-star binaries. The non-thermal radiation is due to synchrotron emission in the colliding-wind region. Cyg O…
Is the bowshock of the runaway massive star HD 195592 a Fermi source?
M. V. del Valle, G. E. Romero, M. De Becker
HD 195592 is an O-type super-giant star, known as a well-established runaway. Recently, a Fermi gamma-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 1955…
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.…
The long period eccentric orbit of the particle accelerator HD167971 revealed by long baseline interferometry
M. De Becker, H. Sana, O. Absil +2
Using optical long baseline interferometry, we resolved for the first time the two wide components of HD167971, a candidate hierarchical triple system known to efficiently accelera…
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…
Tests with a Carlina-type diluted telescope; Primary coherencing
H. Le Coroller, J. Dejonghe, X. Regal +10
Studies are under way to propose a new generation of post-VLTI interferometers. The Carlina concept studied at the Haute- Provence Observatory is one of the proposed solutions. It…
