Dust Processing and Grain Growth in Protoplanetary Disks in the Taurus-Auriga Star-Forming Region

B. A. Sargent, W. J. Forrest, C. Tayrien +9

Mid-infrared spectra of 65 T Tauri stars (TTS) taken with the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope are modeled using dust at two temperatures to probe t…

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…

Observational m Interstellar Extinction Curves Toward Star-Forming Regions Derived from Spitzer IRS Spectra

M. K. McClure

Using \emph{Spitzer} Infrared Spectrograph observations of G0--M4 III stars behind dark clouds, I construct m empirical extinction curves for , which is equiv…

A sub-AU outwardly truncated accretion disk around a classical T Tauri star

M. K. McClure, W. J. Forrest, B. A. Sargent +10

We present the Spitzer Infrared Spectrograph (IRS) spectrum of SR20, a 5--10 AU binary T Tauri system in the Ophiuchi star forming region. The spectrum has features consistent…

Spitzer IRS Spectra and Envelope Models of Class I Protostars in Taurus

E. Furlan, M. McClure, N. Calvet +8

We present Spitzer Infrared Spectrograph spectra of 28 Class I protostars in the Taurus star-forming region. The 5 to 36 micron spectra reveal excess emission from the inner region…
