Imaging the Cool Hypergiant NML Cygni's Dusty Circumstellar Envelope with Adaptive Optics
M. T. Schuster, M. Marengo, J. L. Hora +6
We present sub-arcsec angular resolution, high-Strehl ratio mid-IR adaptive optics images of the powerful OH/IR source and cool hypergiant NML Cyg at 8.8, 9.8 and 11.7 um. These im…
A multi-scale study of infrared and radio emission from Scd galaxy M33
F. S. Tabatabaei, R. Beck, M. Krause +9
We investigate the energy sources of the infrared (IR) emission and their relation to the radio continuum emission at various spatial scales within the Scd galaxy M33. We use the w…
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…
