Gravitational instability in binary protoplanetary disks
We review the models and results of simulations of self-gravitating, gaseous protoplanetary disks in binary star systems. These models have been calculated by three different groups with three different computational methods, two particle-based and one grid-based. We show that interactions with the companion star can affect the temperature distribution and structural evolution of disks, and dis...
متن کاملMassive Protoplanetary Disks in the Trapezium Region
We determine the disk mass distribution around 336 stars in the young (∼ 1 Myr) Orion Nebula cluster by imaging a 2. 5 × 2. 5 region in λ3 mm continuum emission with the Owens Valley Millimeter Array. For this sample of 336 stars, we observe 3 mm emission above the 3σ noise level toward ten sources, six of which have also been detected optically in silhouette against the bright nebular backgrou...
متن کاملInside-out Evacuation of Transitional Protoplanetary Disks by the Magneto-rotational Instability
How do T Tauri disks accrete? The magneto-rotational instability (MRI) supplies one means, but protoplanetary disk gas is typically too poorly ionized to be magnetically active. Here we show that the MRI can, in fact, explain observed accretion rates for the sub-class of T Tauri disks known as transitional systems. Transitional disks are swept clean of dust inside rim radii of ∼10 AU. Stellar c...

متن کاملRotational Line Emission from Water in Protoplanetary Disks
Circumstellar disks provide the material reservoir for the growth of young stars and for planet formation. We combine a high-level radiative transfer program with a thermal-chemical model of a typical T Tauri star disk to investigate the diagnostic potential of the far-infrared lines of water for probing disk structure. We discuss the observability of pure rotational H2O lines with the Herschel...
