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…
Towards a Spectral Technique for Determining Material Geometry Around Evolved Stars: Application to HD 179821
J. Nordhaus, I. Minchev, B. Sargent +6
HD 179821 is an evolved star of unknown progenitor mass range (either post-Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral energy distribution (…
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…
HD 98800: A 10-Myr-Old Transition Disk
E. Furlan, B. Sargent, N. Calvet +7
We present the mid-infrared spectrum, obtained with the Spitzer Infrared Spectrograph (IRS), of HD 98800, a quadruple star system located in the 10-Myr-old TW Hydrae association. I…
Crystalline silicates and dust processing in the protoplanetary disks of the Taurus young cluster
Dan M. Watson, Jarron M. Leisenring, Elise Furlan +15
We characterize the crystalline silicate content and spatial distribution of small dust grains in a large sample of protoplanetary disks in the Taurus-Auriga young cluster, using S…
