Description

One of the most outstanding stellar object in our Galaxy, eta Carinae, a colliding wind binary with the largest mass loss rate observed, presents a hard X-ray emission and is therefore a primary candidate to search for particle acceleration by probing its gamma-ray emission. The detection of eta Carinae at high energy through analysis of Fermi/LAT data between 0.2 to 100 GeV was reported in Farnier et al., 2011. A modeling of multi-wavelength observations in which the non-thermal emission due to inverse Compton scattering of UV photons by electrons and pi0 decay of accelerated hadrons arising from the colliding wind region was proposed. I will present the latest results derived from eta Carinae high energy observations.
