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 …

We present the first ultraviolet and optical images of η Car and its circumstellar Homunculus
nebula, obtained with the Advanced Camera for Surveys/High Resolution Camera …

Aims. The role of episodic mass loss is one of the outstanding questions in massive star
evolution. The structural inhomogeneities and kinematics of their nebulae are tracers of their …

In this paper, new two-dimensional hydrodynamical simulations of η Car's nebulae are
performed. In the 1840s, the massive star η Car suffered a major eruption that resulted in the …

In this work, we present new 2D hydrodynamical simulations of the major eruption of η Car
in the 1840s, which resulted in the formation of a bipolar nebula that is commonly known as …

We analyse eight epochs of Hubble Space Telescope Hα+[N ii] imaging of η Carinae's outer
ejecta. Proper motions of nearly 800 knots reveal that the detected ejecta are divided into …

We investigate, using the modelling code shape, the three-dimensional structure of the
bipolar Homunculus nebula surrounding Eta Carinae as mapped by new ESO Very Large …

Our primary goal is to constrain the physical properties of Eta Car's wind-wind collision
region and the properties of Eta Car B, the hot, very massive secondary companion that is …

Abstract Three-dimensional (3D) printing moves beyond interactive 3D graphics and
provides an excellent tool for both visual and tactile learners, since 3D printing can now …

Abstract The “Homunculus” nebula around Eta Carinae is one of our most valuable tools for
understanding the extreme nature of episodic pre-supernova mass loss in the most massive …
