We present the results of extensive observations by the gamma-ray AGILE satellite of the
Galactic region hosting the Carina nebula and the remarkable colliding wind binary Eta …

The X-ray emission from the supermassive star η Car is simulated using a 3D model of the
wind–wind collision. In the model the intrinsic X-ray emission is spatially extended and …

Context. The periodicity of 5.5 years for some observational events occurring in η Carinae
manifests itself across a large wavelength range and has been associated with its binary …

We use the accretion model to explain the early exit of η Car from its 2009 X-ray minimum. In
the accretion model, the secondary star accretes mass from the primary wind near periastron …

We propose an explanation for the puzzling appearance of a wide blue absorption wing in
the He iλ10830 Å P Cygni profile of the massive binary star η Car several months before …

Nesta tese foi feito um estudo dos eventos cíclicos em Carinae em diversas faixas
espectrais. A presença de um buraco na região polar do Homúnculo foi confirmada pelos …
