The final evolution of stars in the mass range 70–140${\text {}}{M} _ {\odot} $ is explored.
Depending upon their mass loss history and rotation rates, these stars will end their lives as …

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 …

Abstract e-ASTROGAM ('enhanced ASTROGAM') is a breakthrough Observatory space
mission, with a detector composed by a Silicon tracker, a calorimeter, and an …

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 …

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 …

We present a set of numerical experiments designed to systematically investigate how
turbulence and magnetic fields influence the morphology, energetics, and dynamics of …

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 …

Recent work suggests that the mass-loss rate of the primary star ηA in the massive colliding
wind binary η Carinae dropped by a factor of 2–3 between 1999 and 2010. We present …

We present a three-dimensional (3D) dynamical model for the broad [Fe iii] emission
observed in η Carinae using the Hubble Space Telescope/Space Telescope Imaging …
