Contrary to recent claims, we argue that the orientation of the massive binary system Eta
Carinae is such that the secondary star is closer to us at periastron passage, and it is on the …

We show that recent observations of He i and N ii lines of η Carinae may provide support for
an orbital orientation where the secondary star is closest to us at periastron passages. This …

I examine some aspects of the interaction between the massive star η Carinae and its
companion, in particular during the eclipse-like event, known as the spectroscopic event or …

The 1992.5 and 1998.0 low-excitation events of the possible binary in the core of η Carinae
show a conspicuous flare-like event in optical and near-ultraviolet light. These events last a …

Abstract Eta Carinae (η Car) exhibits a unique set of P Cygni profiles with both broad and
narrow components. Over many decades, the spectrum has changed—there has been an …

ABSTRACT η Carinae is an extremely luminous and energetic colliding-wind binary. The
combination of its orbit and orientation, with respect to our line of sight, enables direct …

We use recent observations of the He i λ10 830 Å absorption line and 3D hydrodynamical
numerical simulations of the winds collision to strengthen the case for an orientation of the …

We discuss the events that led to the giant eruption of Eta Carinae, and find that the mid-
nineteenth century (in 1838–1843) giant mass-loss outburst has the characteristics of being …

We have analyzed high spatial, moderate spectral resolution observations of η Carinae (η
Car) obtained with the STIS from 1998.0 to 2004.3. The data were obtained at discrete times …

FUV spectra of η Car, recorded across two decades with HST/STIS, document multiple
changes in resonant lines caused by dissipating extinction in our line of sight. The FUV flux …
