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…
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…
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…
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…
A Two Hour Quasi-Period in an Ultra-luminous X-Ray source in NGC628
Ji-Feng Liu, Joel N. Bregman, Ed Lloyd-Davies +3
Quasi-periodic oscillations and X-ray spectroscopy are powerful probes of black hole masses and accretion disks, and here we apply these diagnostics to an ultraluminous X-ray sourc…
