Long-wavelength excesses of FU Orionis objects: flared outer disks or infalling envelopes?
Zhaohuan Zhu, Lee Hartmann, Nuria Calvet +3
The mid- to far-infrared emission of the outbursting FU Orionis objects has been attributed either to a flared outer disk or to an infalling envelope. We revisit this issue using d…
Constraining the Envelope Structure of L1527 IRS: Infrared Scattered Light Modeling
John J. Tobin, Lee Hartmann, Nuria Calvet +1
We model Spitzer Space Telescope observations of the Taurus Class 0 protostar L1527 IRS (IRAS 04368+2557) to provide constraints on its protostellar envelope structure. The nearly…
Spitzer IRS Observations of Disks around Brown Dwarfs in the TW Hydra Association
A. L. Morrow, K. L. Luhman, C. Espaillat +8
Using SpeX at the NASA Infrared Telescope Facility and the Spitzer Infrared Spectrograph, we have obtained infrared spectra from 0.7 to 30um for three young brown dwarfs in the TW…
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…
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…
