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…
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…
Probing the Dust and Gas in the Transitional Disk of CS Cha with Spitzer
Catherine Espaillat, Nuria Calvet, Paola D'Alessio +10
Here we present the Spitzer IRS spectrum of CS Cha, a member of the ~2 Myr old Chamaeleon star-forming region, which reveals an optically thick circumstellar disk truncated at ~43…
