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 …

In order to study the distribution of gas and ionizing radiation around η Car and their implications for its likely companion star, we have examined high-excitation emission lines …

We present two-dimensional (2D) radiative transfer modelling of the Eta Carinae binary system accounting for the presence of a wind–wind collision (WWC) cavity carved in the …

Recent work suggests that the mass-loss rate of the primary star ηA in the massive colliding wind binary η Carinae dropped by a factor of 2–3 between 1999 and 2010. We present …
We present a three-dimensional (3D) dynamical model for the broad [Fe iii] emission observed in η Carinae using the Hubble Space Telescope/Space Telescope Imaging …

We reconstruct the evolution of η Car in the last two centuries under the assumption that the two 19th century eruptions were triggered by periastron passages and through this …

ABSTRACT Eta Carinae (η Car) is an extremely massive binary system in which rapid spectrum variations occur near periastron. Most notably, near periastron the He ii λ4686 line …
