The interacting binary Eta Carinae remains one of the most enigmatic massive stars in our Galaxy despite over four centuries of observations. In this work, its light curve from the ultraviolet to the near-infrared is analysed using spatially resolved HST observations and intense monitoring at the La Plata Observatory, combined with previously published photometry. We have developed a method to separate the central stellar object in the ground-based images using HST photometry and applying it to… Expand
Eta carinae and the homunculus: far infrared/submillimetre spectral lines detected with the Herschel Space Observatory
The evolved massive binary star Eta Carinae underwent eruptive mass loss events that formed the complex bi-polar Homunculus nebula harboring tens of solar masses of unusually nitrogen-rich gas andExpand
Mid-infrared evolution of η Carinae from 1968 to 2018
η Car is one of the most luminous and massive stars in our Galaxy and is the brightest mid-IR source in the sky outside our solar system. Since the late 1990s, the central source has dramaticallyExpand
CO, Water, and Tentative Methanol in η Carinae Approaching Periastron
In circumstellar gas, the complex organic molecule methanol has been found almost exclusively around young stellar objects, and is thus regarded as a signpost of recent star formation. Here we reportExpand
The peculiar chemistry of the inner ejecta of Eta Carina
We investigated continuum and molecular line emission of four species (CO, HCN, H13CN, and HCO+) at 0.8 mm in the inner region around η Car, using ALMA archival observations at a resolution betterExpand
Soft and hard X-ray dips in the light curves of γ Cassiopeiae
The available six archival XMM–Newton observations of the anomalous X-ray emitter γ Cas (B0.5 IVe) have been surveyed for the presence of soft X-ray ‘dips’ in X-ray light curves. In addition toExpand
η Carinae: high angular resolution continuum, H30α and He30α ALMA images
We present images of $\eta$ Carinae in the recombination lines H30$\alpha$ and He30$\alpha$ and the underlying continuum with 50~mas resolution (110 AU), obtained with ALMA. For the first time, theExpand
One of Everything: The Breakthrough Listen Exotica Catalog
We present Breakthrough Listen’s Exotica Catalog as the centerpiece of our efforts to expand the diversity of targets surveyed in the Search for Extraterrestrial Intelligence (SETI). As motivation,Expand
Spectroscopic signatures of the vanishing natural coronagraph of Eta Carinae
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 last 80 years. AnExpand
The X-Ray Properties of Eta Carinae During Its 2020 X-Ray Minimum
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 emissionExpand


Mid-cycle changes in eta Carinae
In late 2006, ground-based photometry of {eta} Car plus the Homunculus showed an unexpected decrease in its integrated apparent brightness, an apparent reversal of its long-term brightening.Expand
BRITE-Constellation reveals evidence for pulsations in the enigmatic binary η Carinae
$\eta$ 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 nanosatellites over 6 monthsExpand
Herschel far-infrared observations of the Carina Nebula complex II: The embedded young stellar and protostellar population
Context. The Carina Nebula represents one of the largest and most active star forming regions known in our Galaxy. It contains numerous very massive (M > 40 M� ) stars that strongly affect theExpand
Eta Carinae across the 2003.5 Minimum: Deciphering the Spectrum toward Weigelt D

Recent Changes in the Near-Ultraviolet and Optical Structure of η Carinae
Multiepoch HST/WFPC2 images of η Carinae are used to investigate the relationship between the photometric variability of the circumstellar nebula and the variability of the central star. In the pastExpand
Near-Infrared Evidence for a Sudden Temperature Increase in Eta Carinae
Aims. Eta Car's ultra-violet, optical, and X-ray light curves and its spectrum suggest a physical change in its stellar wind over the last decade. It was proposed that the mass-loss rate decreased byExpand
Long-term optical monitoring of η Carinae - Multiband light curves for a complete orbital period
Context. The periodicity of 5.5 years for some observational events occurring in η  Carinae manifests itself across a large wavelength range and has been associated with its binary nature. TheseExpand
