Modeling the RXTE light curve of Carinae from a 3-D SPH simulation of its binary wind collision
A. T. Okazaki, S. P. Owocki, C. M. Russell +1
The very massive star system Carinae exhibits regular 5.54-year (2024-day) period disruptive events in wavebands ranging from the radio to X-ray. There is a growing consensus t…
New insights into the nature of the SMC WR/LBV binary HD 5980
C. Foellmi, G. Koenigsberger, L. Georgiev +14
We present the results of optical wavelength observations of the unusual SMC eclipsing binary system HD 5980 obtained in 1999 and 2004--2005. Radial velocity curves for the eruptin…
X-ray Spectral Variation of Eta Carinae through the 2003 X-ray Minimum
Kenji Hamaguchi, Michael F. Corcoran, Theodore Gull +7
We report the results of an X-ray observing campaign on the massive, evolved star Eta Carinae, concentrating on the 2003 X-ray minimum as seen by the XMM-Newton observatory. These…
Eta Carinae across the 2003.5 minimum: Spectroscopic Evidence for Massive Binary Interactions
K. E. Nielsen, M. F. Corcoran, T. R. Gull +4
We have analyzed high spatial, moderate spectral resolution observations of Eta Carinae obtained with the STIS from 1998.0 to 2004.3. The spectra show prominent P-Cygni lines in H…
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…
An X-ray investigation of the NGC 346 field in the SMC (3): XMM-Newton data
Yaël Nazé, Jean Manfroid, Ian R. Stevens +2
We present new XMM-Newton results on the field around the NGC346 star cluster in the SMC. This continues and extends previously published work on Chandra observations of the same f…
