The feedback of massive stars on interstellar astrochemical processes
Michael De Becker
Astrochemistry is a discipline that studies physico-chemical processes in astrophysical environments. Such environments are characterized by conditions that are substantially diffe…
WR 138: new results from X-ray and optical spectroscopy
M. Palate, G. Rauw, M. De Becker +2
Context. Massive-binary evolution models predict that some systems will go through an evolutionary phase where the original primary has become a supernova and left a compact object…
Catalogue of particle-accelerating colliding-wind binaries
M. De Becker, F. Raucq
Massive systems made of two or more stars are known to be the site for interesting physical processes -- including at least in some cases -- particle acceleration. Over the past de…
The Hot and Energetic Universe: Star formation and evolution
S. Sciortino, G. Rauw, M. Audard +16
Stars over a wide range of masses and evolutionary stages are nowadays known to emit X-rays. This X-ray emission is a unique probe of the most energetic phenomena occurring in the…
Astrochemistry: the issue of molecular complexity in astrophysical environments
M. De Becker
Astrochemistry aims at studying chemical processes in astronomical environments. This discipline -- located at the crossroad between astrophysics and chemistry -- is rapidly evolvi…
The X-ray under-luminosity of the O-type supergiants HD16691 and HD14947 revealed by XMM-Newton
M. De Becker
The members of the scarce category of Of^+ supergiants present properties that are intermediate between regular O-stars and Wolf-Rayet (WR) stars. Significant similarities between…
Three-dimensional orbits of the triple-O stellar system HD 150136
H. Sana, J. -B. Le Bouquin, L. Mahy +3
Context. HD 150136 is a triple hierarchical system and a non-thermal radio emitter. It is formed by an O3-3.5 V + O5.5-6 V close binary and a more distant O6.5-7 V tertiary. So far…
Multiwavelength Observations of Gamma-ray Binary Candidates
M. Virginia McSwain, Masha Chernyakova, Denis Malishev +2
A rare group of high mass X-ray binaries (HMXBs) are known that also exhibit MeV, GeV, and/or TeV emission ("gamma-ray binaries"). Expanding the sample of gamma-ray binaries and id…
A spectroscopic investigation of the O-type star population in four Cygnus OB associations. I. Determination of the binary fraction
L. Mahy, G. Rauw, M. De Becker +2
Context. Establishing the multiplicity of O-type stars is the first step towards accurately determining their stellar parameters. Moreover, the distribution of the orbital paramete…
