After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

Starforming factories in galaxies produce compact clusters and loose associations of young
massive stars. Fast radiation-driven winds and supernovae input their huge kinetic power …

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 …

This catalog summarizes 117 high-confidence⩾ 0. 1 GeV gamma-ray pulsar detections
using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite …

Massive systems made of two or more stars are known to be the site for interesting physical
processes–including at least in some cases–particle acceleration. Over the past decade, this …

Context. This is the second paper of a series on Galactic OB groups that uses astrometric
and photometric data from Gaia and spectral classifications from the Galactic O-Star …

We present the results of extensive observations by the gamma-ray AGILE satellite of the
Galactic region hosting the Carina nebula and the remarkable colliding wind binary Eta …

The X-ray emission from the supermassive star η Car is simulated using a 3D model of the
wind–wind collision. In the model the intrinsic X-ray emission is spatially extended and …

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 …
