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 …

The massive binary system Eta Carinae is characterized by intense colliding winds that form
shocks and emit X-rays. The system is highly eccentric (e≃ 0.9), resulting in modulated X-ray …

Abstract η Car is a massive, eccentric binary with a rich observational history. We obtained
the first high-cadence, high-precision light curves with the BRITE-Constellation …

The massive binary system formed by η Car and an unknown companion is a strong source
at millimetre and submillimetre wavelengths. Close to the stars, continuum bremsstrahlung …

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 …

Single-dish submillimeter observations have recently revealed the existence of a
substantial, chemically peculiar molecular gas component located in the innermost …

Eta Carinae underwent the Great Eruption in the 1840s and a Lesser Eruption in the 1890s.
Its apparent spectrum, modified by intervening ejecta, the Homunculus and Little …

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 …

The nature and origin of the molecular gas component located in the circumstellar vicinity of
η Carinae are still far from being completely understood. Here, we present Atacama Large …

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 …
