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

Doppler spectroscopy is a powerful tool for discovering and characterizing exoplanets. For
decades, the standard approach to extracting radial velocities (RVs) has been to cross …

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 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 …

The Na D absorption doublet in the spectrum of η Carinae is complex, with multiple
absorption features associated with the Great Eruption (1840s), the Lesser Eruption (1890s) …

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 …

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 …

Aims. Every 5.5 years, η Car's light curve and spectrum change remarkably across all
observed wavelength bands. These so-called spectroscopic events are most likely caused …

The binary η Carinae is the closest example of a very massive star, which may have formed
through a merger during its Great Eruption in the mid-19th century. We aimed to confirm and …
