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

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 …

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 …

The very massive star system η Carinae exhibits regular 5.54 yr (2024 d) period disruptive
events in wavebands ranging from the radio to X-ray. There is a growing consensus that …

We report continued monitoring of the superluminous binary system η Car by the
Proportional Counter Array on the Rossi X-ray Timing Observatory (RXTE) through the 2009 …

We solve the Rossi X-Ray Timing Explorer X-ray light curve of the extremely luminous and
massive star η Carinae with a colliding-wind emission model to refine the ground-based …

We study the usage of the X-ray light curve, column density towards the hard X-ray source,
and emission measure (density square times volume), of the massive binary system η …

We report high-precision X-ray monitoring observations in the 0.4–10 keV band of the
luminous, long-period colliding wind binary Eta Carinae, up to and through its most recent X …

The exact nature of η Carinae is still an open issue. Strict periodicity in the light curves at
several wavelengths seem to point to a binary system, but the observed radial velocities …

Spectral observations of the massive colliding wind binary Eta Carinae show phase-
dependent variations, in intensity and velocity, of numerous helium emission and absorption …
