Onthe changes in the physical properties of the ionized region around the Weigelt structures in η Carinae over the 5.54-yr spectroscopic cycle
We present HST/STIS observations and analysis of two prominent nebular structures around
the central source of η Carinae, the knots C and D. The former is brighter than the latter for …

Prediction for the He iλ10830 Å absorption wing in the coming event of η Carinae
We propose an explanation for the puzzling appearance of a wide blue absorption wing in
the He iλ10830 Å P Cygni profile of the massive binary star η Car several months before …

Wind collision and accretion simulations of the massive binary system HD 166734
A Kashi - Monthly Notices of the Royal Astronomical Society, 2020 - academic.oup.com
ABSTRACT I have run hydrodynamic simulations that follow the colliding wind structure of
the massive binary system HD 166734 along its binary orbit. I show that close to periastron …

The Orientation of Eta Carinae and the Powering Mechanism of Intermediate-luminosity Optical Transients (ILOTS)
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 …

[PDF][PDF] The Eta Carinae Homunculus in Full 3D with X-shooter and Shape
Massive stars like Eta Carinae are extremely rare in comparison to stars such as the Sun,
and currently we know of only a handful of stars with masses of more than 100 M in the Milky …

Explaining the transient fast blue absorption lines in the massive binary system η Carinae
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 …
