Polycyclic Aromatic Hydrocarbons Orbiting HD 233517, an Evolved Oxygen-Rich Red Giant
M. Jura, J. Bohac, B. Sargent +7
We report spectra obtained with the Spitzer Space Telescope in the 5 to 35 micron range of HD 233517, an evolved K2 III giant with circumstellar dust. At wavelengths longer than 13…
Mid-infrared spectra of PAH emission in Herbig AeBe stars
G. C. Sloan, L. D. Keller, W. J. Forrest +16
We present spectra of four Herbig AeBe stars obtained with the Infrared Spectrograph (IRS). on the Spitzer Space Telescope. All four of the sources show strong emission from polycy…
Spitzer detections of new dust components in the outflow of the Red Rectangle
F. Markwick-Kemper, J. D. Green, E. Peeters
We present Spitzer high spectral resolution IRS spectroscopy of three positions in the carbon-rich outflow of post-AGB star HD 44179, better known as the Red Rectangle. Surprisingl…
Solid state components of varying compositions in the outflow of the Red Rectangle
F. Kemper, J. D. Green, E. Peeters
We present high resolution Spitzer spectroscopy of several pointings in the outflow of the Red Rectangle. Besides the resonances due to the C-rich PAHs, the spectra show a wealth o…
