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…
FUSE Observations of eta Carinae
R. C. Iping, G. Sonneborn, T. R. Gull
Eta Carinae was observed by FUSE through the LWRS (30 arcsec x30 arcsec) and HIRS (1.25 arcsec x 20 arcsec) apertures in March and April 2004. There are significant differences bet…
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…
STIS Near Ultraviolet Time-Tagged Spectra of the Crab Pulsar
Theodore R. Gull, Don J. Lindler, D. Michael Crenshaw +8
We present the spectrum and pulse profile of the Crab Pulsar in the near ultraviolet (1600-3200 Angstroms) observed with the Space Telescope Imaging Spectrograph (STIS) during the…
