We have developed a physically self-consistent model of the disk around the nearby 10 Myr old star TW Hya that matches the observed spectral energy distribution and 7 mm images of the disk. The model requires both significant dust-size evolution and a partially evacuated inner disk region, as predicted by theories of planet formation. The outer disk, which extends to at least 140 AU in radius, is very optically thick at infrared wavelengths and quite massive (~0.06 M☉) for the relatively…

Toward Planetesimals in the Disk around TW Hydrae: 3.5 Centimeter Dust Emission
We present Very Large Array observations at λ = 3.5 cm of the nearby young star TW Hya that show the emission is constant in time over weeks, months, and years, and spatially resolved with peak
A Slowly Accreting ~10 Myr-old Transitional Disk in Orion OB1a
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 distribution of this
The State of Protoplanetary Material 10 Million years after Stellar Formation: Circumstellar Disks in the TW Hydrae Association
We have used the Spitzer Space Telescope Infrared Spectrograph to observe seven members of the TW Hya association, the nearest stellar association whose age (∼10 Myr) is similar to the timescales
HD 98800: A 10 Myr Old Transition Disk
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. It has a known
The Truncated Disk of CoKu Tau/4
We present a model of a dusty disk with an inner hole that accounts for the Spitzer Space Telescope Infrared Spectrograph observations of the low-mass pre-main-sequence star CoKu Tau/4. We have
Circumstellar disks are thought to experience a rapid “transition” phase in their evolution that can have a considerable impact on the formation and early development of planetary systems. We present
Molecular Gas in the Inner 1 AU of the TW Hya and GM Aur Transitional Disks
We report the detection of CO rovibrational emission from the transitional disks around the T Tauri stars TW Hya and GM Aur. Transitional disks are characterized by significant mid- to far-infrared
Large grains in the disk of CQ Tau
We present 7 mm observations of the dusty disk surrounding the 10 Myr old 1.5 Mpre-main-sequence star CQ Tauri obtained at the Very Large Array with 0.8 arcsec resolution and 0.1 mJy rms sensitivity.
The Masses of Transition Circumstellar Disks: Observational Support for Photoevaporation Models
We report deep Submillimeter Array observations of 26 pre-main-sequence (PMS) stars with evolved inner disks. These observations measure the mass of the outer disk (r ∼ 20-100 AU) across every stage
The Evolution of Protoplanetary Disks: Probing the Inner Disk of Very Low Accretors
We report FUV, optical, and NIR observations of three T Tauri stars in the Orion OB1b subassociation with Hα equivalent widths consistent with low or absent accretion and various degrees of excess


Accretion Disks around Young Objects. II. Tests of Well-mixed Models with ISM Dust
We construct detailed vertical structure models of irradiated accretion disks around T Tauri stars with interstellar medium dust uniformly mixed with gas. The dependence of the structure and emission
Spectral Energy Distributions of T Tauri Stars with Passive Circumstellar Disks
We derive hydrostatic, radiative equilibrium models for passive disks surrounding T Tauri stars. Each disk is encased by an optically thin layer of superheated dust grains. This layer reemits
