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 …

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 …

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 …

Asymmetric variability in ultraviolet images of the Homunculus obtained with the Advanced
Camera for Surveys/High Resolution Camera on the Hubble Space Telescope suggests that …

The exact nature of η Carinae is still an open issue. Strict periodicity in the light curves at
several wavelengths seem to point to a binary system, but the observed radial velocities …

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 …

Abstract We present Hubble Space Telescope (HST) Space Telescope Imaging
Spectrograph (STIS) high-resolution near-ultraviolet (NUV) spectra of η Car's central source …

Abstract Since 2002, the far-ultraviolet (FUV) flux (1150–1680 Å) of Eta Carinae, monitored
by the Hubble Space Telescope/Space Telescope Imaging Spectrograph, has increased by …

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 …

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 …
