Physical conditions in the Homunculus
Gary J. Ferland, Nick Abel, Kris Davidson +1
Conditions within the Homunculus nebula around Eta Car are determined by many of the same physical processes that occur in molecular clouds in the interstellar medium. But there is…
XMM-Newton Observations of the 2003 X-ray Minimum of Eta Carinae
K. Hamaguchi, M. F. Corcoran, T. Gull +3
The XMM-Newton X-ray observatory took part in the multi-wavelength observing campaign of the massive, evolved star Eta Carinae in 2003 during its recent X-ray minimum. This paper r…
X-ray Gyrations of Eta Carinae, or, Is Presence of Evidence Evidence of Presence?
M. F. Corcoran, K. Hamaguchi, T. Gull +2
We review the properties of the variable X-ray emission from the extremely massive star Eta Carinae concentrating on the last X-ray minimum, and briefly consider the possible role…
A High-Resolution Study of Eta Carinae's Outer Ejecta
Kerstin Weis, Michael F. Corcoran, Kris Davidson +1
Eta Carinae is a very luminous and unstable evolved star. Outflowing material ejected during the star's giant eruption in 1843 surrounds it as a nebula which consists of an inner b…
On the X-ray emission of Eta Carinae's outer ejecta
Kerstin Weis, Michael F. Corcoran, Kris Davidson
The extremely luminous and unstable star Eta Carinae is surrounded by ejecta formed during the star's giant eruption around 1843. The optical nebula consists of an inner region, th…
Preliminary Analysis of STIS-HST Spectra of Compact Ejecta from Eta Carinae
F. Hamann, K. Davidson, K. Ishibashi +1
We describe some preliminary results from spatially-resolved spectroscopy of the compact ejection knots B and D in the Eta Carinae wind. We emphasize various line diagnostics of th…
