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…
