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…
High Resolution, Long - Slit Spectroscopy of VY CMa: The Evidence for Localized High Mass Loss Events
Roberta M. Humphreys, Kris Davidson, Gerald Ruch +1
High spatial and spectral resolution spectroscopy of the OH/IR supergiant VY CMa and its circumstellar ejecta reveals evidence for high mass loss events from localized regions on t…
Waiting in the Wings: Reflected X-ray Emission from the Homunculus Nebula
M. F. Corcoran, K. Hamaguchi, T. Gull +14
We report the first detection of X-ray emission associated with the Homunculus Nebula which surrounds the supermassive star Eta Carinae. The emission is characterized by a temperat…
