Previous generations of X-ray observatories revealed a group of massive binaries that were
relatively bright X-ray emitters. This was attributed to emission of shock-heated plasma in the …

We present multi-epoch photometry and spectroscopy of a light echo from η Carinae's 19th
century Great Eruption. This echo's light curve shows a steady decline over a decade …

Nearly all types of massive stars with radiatively driven stellar winds are X-ray sources that
can be observed by the presently operating powerful X-ray telescopes. In this review I briefly …

The historical light curve of the 19th century 'Great Eruption'of η Carinae provides a striking
record of the violent instabilities encountered by massive stars. In this paper, we report and …

Three-dimensional adaptive mesh refinement hydrodynamical simulations of the wind–wind
collision between the enigmatic supermassive star η Car and its mysterious companion star …

ABSTRACT The Great Nebula in Carina provides an exceptional view into the violent
massive star formation and feedback that typifies giant H ii regions and starburst galaxies …

Doppler spectroscopy is a powerful tool for discovering and characterizing exoplanets. For
decades, the standard approach to extracting radial velocities (RVs) has been to cross …

In order to study the distribution of gas and ionizing radiation around η Car and their
implications for its likely companion star, we have examined high-excitation emission lines …

ABSTRACT We report the Fermi Large Area Telescope (Fermi-LAT) detection of the γ-ray
emission toward the massive star forming region of Carina Nebula Complex (CNC). Using …

We present two-dimensional (2D) radiative transfer modelling of the Eta Carinae binary
system accounting for the presence of a wind–wind collision (WWC) cavity carved in the …
