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 …

ABSTRACT A series of three Hubble Space Telescope/Space Telescope Imaging
Spectrograph spectroscopic mappings, spaced approximately one year apart, reveal three …

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

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 …

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 …

The very massive star system η Carinae exhibits regular 5.54 yr (2024 d) period disruptive
events in wavebands ranging from the radio to X-ray. There is a growing consensus that …

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 …

Eta Carinae, the closest, active, massive binary containing a highly unstable Luminous Blue
Variable, exhibits expanding, compressed wind shells, seen in emission, that are spatially …

Aims. The binary system η Carinae has completed its first 5.54 y orbit since the beginning of
science operation of the Fermi Large Area Telescope (LAT). We are now able to investigate …
