We report on Swift X-ray Telescope observations of Eta Carinae (η Car), an extremely
massive, long-period, highly eccentric binary obtained during the 2014.6 X-ray …

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 report the results of an observing campaign on η Car around the 2003 X-ray minimum,
mainly using the XMM-Newton observatory. These are the first spatially resolved X-ray …

We present monitoring observations by the Rossi X-Ray Timing Explorer of the 2–10 keV X-
ray emission from the supermassive star η Carinae from 1996 through late 2003. These data …

The evolved, massive highly eccentric binary system, η Car, underwent a periastron
passage in the summer of 2014. We obtained two coordinated X-ray observations with XMM …

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 use the accretion model to explain the early exit of η Car from its 2009 X-ray minimum. In
the accretion model, the secondary star accretes mass from the primary wind near periastron …

ABSTRACT X-ray emission from the supermassive binary system η Car declines sharply
around periastron. This X-ray minimum has two distinct phases—the lowest flux phase in the …

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 …
