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 Change in the Physical State of Carinae?
K. Davidson, J. C. Martin, R. M. Humphreys +8
During Car's spectroscopic event in mid-2003, the stellar wind's bright H and H emission lines temporarily had a distinctive shape unlike that reported on any previous oc…
X-ray and radio emission from colliding stellar winds
J. M. Pittard, S. M. Dougherty, R. F. Coker +1
The collision of the hypersonic winds in early-type binaries produces shock heated gas, which radiates thermal X-ray emission, and relativistic electrons, which emit nonthermal rad…
A Period and a Prediction for the Of?p Spectrum Alternator HD 191612
Nolan R. Walborn, Ian D. Howarth, Gregor Rauw +7
The observational picture of the enigmatic O-type spectrum variable HD191612 has been sharpened substantially. A symmetrical, low-amplitude light curve with a period near 540 d has…
Probing Colliding Wind Binaries with High-Resolution X-ray Spectra
D. B. Henley, I. R. Stevens, J. M. Pittard +2
X-ray line profiles represent a new way of studying the winds of massive stars. In particular, they enable us to probe in detail the wind-wind collision in colliding wind binaries,…
Multi-Wavelength Observations of Colliding Stellar Winds
M. F. Corcoran, J. M. Pittard, I. R. Stevens +2
Massive colliding wind binary stars serve as laboratories for the study of strong-shock physics. In these systems fundamental flow parameters (velocities, densities, directions) ar…
Chandra Observation of the Trifid Nebula: X-ray emission from the O star complex and actively forming pre-main sequence stars
J. Rho, S. Ramirez, M. F. Corcoran +2
The Trifid Nebula, a young star-forming HII region, was observed for 16 hours by the Chandra X-ray Observatory. We detected 304 X-ray sources, thirty percent of which are hard sour…
