On the He II Emission In Eta Carinae and the Origin of Its Spectroscopic Events
J. C. Martin, K. Davidson, R. M. Humphreys +2
We describe and analyze Hubble Space Telescope (HST) observations of transient emission near 4680 Å in Eta Car, reported earlier by Steiner & Damineli (2004). If, as seems probable…

VLT-UVES observations of the Balmer line variations of eta Carinae during the 2003 spectroscopic event
Kerstin Weis, Otmar Stahl, Dominik J. Bomans +3
We present high spectral resolution echelle observations of the Balmer line variations during the 2003.5 ``spectroscopic event'' of eta Carinae. Spectra have been recorded of both…

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…
