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 …

We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in
the 100 MeV–300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma …

Le domaine de l'astronomie gamma a connu des progrès impressionnants au cours de la
dernière décennie. Grâce à l'avènement d'une nouvelle génération de télescopes …

More than a dozen binary systems are now established as sources of variable, high-energy
(HE, 0.1–100 GeV) gamma rays. Five are also established sources of very-high-energy …

Aims. The binary system η Carinae has completed its first 5.54 y orbit since the beginning of
science operation of the Fermi Large Area Telescope (LAT). We are now able to investigate …

Aims. Despite recent progress in the field, there are still many open questions regarding γ-
ray binaries. In this paper we provide an overview of non-transient γ-ray binaries and …

Gamma-ray emitting binaries (GREBs) are complex systems. Its study became in the last
years a major endeavour for the high-energy astrophysics community, both from an …

Aims. Colliding wind binary systems have long been suspected to be high-energy (HE; 100
MeV< E< 100 GeV) γ-ray emitters. η Car is the most prominent member of this object class …

In this paper, we present the Fermi All-sky Variability Analysis (FAVA), a tool to
systematically study the variability of the gamma-ray sky measured by the Large Area …

The binary stellar system η Carinae is one of very few established astrophysical hadron
accelerators. It seems likely that at least some fraction of the particles accelerated by η …
