Abstract	Relativistic particle acceleration takes place in colliding-wind binaries, thus leading to the emission of soft gamma-rays through inverse Compton scattering. Such a non-thermal emission has been recently detected for the ?rst time in Eta Carinae by INTEGRAL. The averaged emission from Eta Carinae in the 22?100 keV energy range is very hard (photon index around 1) and its luminosity is 7E33 erg/s. The X-ray emission of Eta Carinae is changing along its orbital period of 5.53 yr, and there are hints that the same might apply to its gamma-ray emission. Therefore, we propose to perform a 1 Ms observation of Eta Carinae around December 2008, during the next periastron passage.

Mission Description	The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
