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 …

We analyze spatially resolved spectroscopic observations of the Eta Carinae binary system
obtained with the Hubble Space Telescope/STIS. Eta Car is enshrouded by the dusty …

Spectral observations of the massive colliding wind binary Eta Carinae show phase-
dependent variations, in intensity and velocity, of numerous helium emission and absorption …

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 …

ABSTRACT The interacting binary Eta Carinae remains one of the most enigmatic massive
stars in our Galaxy despite over four centuries of observations. In this work, its light curve …

We analyze interferometric measurements of the luminous blue variable Eta Carinae with
the goal of constraining the rotational velocity of the primary star and probing the influence of …

We present a new model for the behavior of scattered time-dependent, asymmetric near-UV
emission from the nearby ejecta of η Car. Using a three-dimensional (3D) hydrodynamical …

The highly eccentric binary system Eta Carinae (η Car) shows numerous time-variable
emission and absorption features. These observational signatures are the result of …

The highly eccentric binary system, η Car, provides clues to the transition of massive stars
from hydrogen–burning via the CNO cycle to a helium–burning evolutionary state. The fast …

We modelled the He iiλ4686 line profiles observed in the η Carinae binary system close to
the 2003.5 spectroscopic event, assuming that they were formed in the shocked gas that …
