Spitzer Observations of Deeply Obscured Galactic Nuclei
H. W. W. Spoon, J. V. Keane, J. Cami +4
We report on our first results from a mid-infrared spectroscopic study of ISM features in a sample of deeply obscured ULIRG nuclei using the InfraRed Spectrograph (IRS) on the Spit…
Hot Organic Molecules Toward a Young Low-Mass Star: A Look at Inner Disk Chemistry
F. Lahuis, E. F. van Dishoeck, A. C. A. Boogert +8
Spitzer Space Telescope spectra of the low mass young stellar object (YSO) IRS 46 (L_bol ~ 0.6 L_sun) in Ophiuchus reveal strong vibration-rotation absorption bands of gaseous C2H2…
C2D Spitzer-IRS spectra of disks around T Tauri stars: I. Silicate emission and grain growth
J. E. Kessler-Silacci, J. -C. Augereau, C. P. Dullemond +10
Infrared ~5--35 um spectra for 40 solar-mass T Tauri stars and 7 intermediate-mass Herbig Ae stars with circumstellar disks were obtained using the Spitzer Space Telescope as part…
Protostellar holes: Spitzer Space Telescope observations of the protostellar binary IRAS16293-2422
J. K. Jorgensen, F. Lahuis, F. L. Schoeier +7
Mid-infrared (23-35 micron) emission from the deeply embedded "Class 0" protostar IRAS16293-2422 is detected with the Spitzer Space Telescope infrared spectrograph. A detailed radi…
