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 report near-infrared spectroscopic observations of the Eta Carinae massive binary
system during 2008–2009 using the CRIRES spectrograph mounted on the 8 m UT 1 Very …

The X-ray emission of η Carinae shows multiple features at various spatial and temporal
scales. The central constant emission (CCE) component is centred on the binary and arises …

We study the usage of the X-ray light curve, column density towards the hard X-ray source,
and emission measure (density square times volume), of the massive binary system η …

The massive binary system Eta Carinae is characterized by intense colliding winds that form
shocks and emit X-rays. The system is highly eccentric (e≃ 0.9), resulting in modulated X-ray …

We present high-resolution numerical simulations of the colliding wind system η Carinae,
showing accretion on to the secondary star close to periastron passage. Our …

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 …

Contrary to recent claims, we argue that the orientation of the massive binary system Eta
Carinae is such that the secondary star is closer to us at periastron passage, and it is on the …

We use recent observations of the He i λ10 830 Å absorption line and 3D hydrodynamical
numerical simulations of the winds collision to strengthen the case for an orientation of the …

We run numerical simulations of massive colliding wind binaries, and quantify the accretion
onto the secondary under different conditions. We set 3D simulation of a LBV–WR system …
