Starforming factories in galaxies produce compact clusters and loose associations of young
massive stars. Fast radiation-driven winds and supernovae input their huge kinetic power …

Three-dimensional adaptive mesh refinement hydrodynamical simulations of the wind–wind
collision between the enigmatic supermassive star η Car and its mysterious companion star …

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 …

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 …

In our ongoing study of η Carinae's light echoes, there is a relatively bright echo that has
been fading slowly, reflecting the 1845–1858 plateau phase of the eruption. A separate …

Context. The mass loss from massive stars is not understood well. η Carinae is a unique
object for studying the massive stellar wind during the luminous blue variable phase. It is …

Context. Eta Carinae is a highly eccentric, massive binary system (semimajor axis~ 15.5 au)
with powerful stellar winds and a phase-dependent wind-wind collision (WWC) zone. The …

Eta Carinae is a massive interacting binary system shrouded in a complex circumstellar
environment whose evolution is the source of the long-term brightening observed during the …
