After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

With the successful realization of the current-generation of ground-based detectors, TeV
Astronomy has entered into a new era. We review recent advances in VHE astronomy …

Internal shocks caused by fluctuations of the outflow velocity are likely to power the radio-to-
IR emission of the compact jets of X-ray binaries. The dynamics of internal shocks and the …

Context. Relativistic jets are ubiquitous in the Universe. In microquasars, especially in high-
mass X-ray binaries, the interaction of jets with the strong winds driven by the massive and …

The very-high-energy (VHE; E> 100 GeV) gamma-ray source HESS J0632+ 057 is a new
member of the elusive class of gamma-ray binaries (Aharonian et al. 2007; Hinton et al …

Context. High-mass gamma-ray binaries are powerful nonthermal galactic sources, some of
them hosting a pulsar whose relativistic wind interacts with a likely inhomogeneous stellar …

Context. Cygnus X-1 is a well-observed microquasar. Broadband observations at all
wavelengths have been collected over the years. The origin of the MeV tail observed with …

High-mass microquasar jets, produced in an accreting compact object in orbit around a
massive star, must cross a region filled with stellar wind. The combined effects of the wind …

The binary systems that have been detected in gamma rays have proven very useful to study
high-energy processes, in particular particle acceleration, emission and radiation …

Context. High-mass microquasars consist of a massive star and a compact object, the latter
producing jets that will interact with the stellar wind. The evolution of the jets, and ultimately …
