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 …

ABSTRACT The interacting binary Eta Carinae remains one of the most enigmatic massive
stars in our Galaxy despite over four centuries of observations. In this work, its light curve …

We use high-resolution 3D hydrodynamical simulations to quantify the amount of mass
accreted on to the secondary star of the binary system Eta Carinae, exploring two sets of …

η Carinae is composed of two very massive stars orbiting each other in 5.5 years. The
primary star features the densest known stellar wind, colliding with that expelled by its …

We present a new model for the non-thermal emission from a colliding-wind binary.
Relativistic protons and electrons are assumed to be accelerated through diffusive shock …

The $\eta $ Carinae binary system is the first $\gamma $-ray binary ever observed which
does not contain a compact object. The dense wind of the primary star shocks against the …
