Silica in Protoplanetary Disks
B. A. Sargent, W. J. Forrest, C. Tayrien +10
Mid-infrared spectra of a few T Tauri stars (TTS) taken with the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope show prominent narrow emission features indicating…
A slowly accreting ~10 Myr old transitional disk in Orion OB1a
C. Espaillat, J. Muzerolle, J. Hernandez +7
Here we present the Spitzer IRS spectrum of CVSO 224, the sole transitional disk located within the ~10 Myr old 25 Orionis group in Orion OB1a. A model fit to the spectral energy d…
Epsilon Eridani's Planetary Debris Disk: Structure and Dynamics based on Spitzer and CSO Observations
D. Backman, M. Marengo, K. Stapelfeldt +9
Spitzer and Caltech Submillimeter Observatory (CSO) images and spectrophotometry of epsilon Eridani at wavelengths from 3.5 to 350 um reveal new details of its bright debris disk.…
On the Diversity of the Taurus Transitional Disks: UX Tau A & Lk Ca 15
C. Espaillat, N. Calvet, P. D'Alessio +5
The recently recognized class of "transitional disk" systems consists of young starswith optically-thick outer disks but inner disks which are mostly devoid of small dust. Here we…
The Dust and Gas Around beta Pictoris
C. H. Chen, A. Li, C. Bohac +12
We have obtained Spitzer IRS 5.5 - 35 micron spectroscopy of the debris disk around beta Pictoris. In addition to the 10 micron silicate emission feature originally observed from t…
A Survey and Analysis of Spitzer Infrared Spectrograph Spectra of T Tauri Stars in Taurus
E. Furlan, L. Hartmann, N. Calvet +9
We present mid-infrared spectra of T Tauri stars in the Taurus star-forming region obtained with the Spitzer Infrared Spectrograph (IRS). For the first time, the 5-36 micron spectr…
