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…
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…
Mid-Infrared Spectroscopy of Disks around Classical T Tauri Stars
W. J. Forrest, B. Sargent, E. Furlan +18
We present the first Spitzer Infrared Spectrograph (IRS; The IRS was a collaborative venture between Cornell University and Ball Aerospace Corporation funded by NASA through the Je…
Dust Processing in Disks around T Tauri Stars
B. Sargent, W. J. Forrest, P. D'Alessio +11
The 8-14 micron emission spectra of 12 T Tauri stars in the Taurus/Auriga dark clouds and in the TW Hydrae association obtained with the Infrared Spectrograph (IRS; The IRS is a co…
