We present the results of a high angular resolution (0.''3 {approx} 40 AU) Submillimeter Array survey of the 345 GHz (870 {mu}m) thermal continuum emission from nine of the brightest, and therefore
Resolved Images of Large Cavities in Protoplanetary Transition Disks
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
Protoplanetary Disk Structures in Ophiuchus. II. Extension to Fainter Sources
We present new results from a significant extension of our previous high angular resolution (03 40 AU) submillimeter array survey of the 340 GHz (880 μm) thermal continuum emission from dusty
Passive Irradiated Circumstellar Disks with an Inner Hole
A model for irradiated dust disks around Herbig Ae stars is proposed. The model is based on the flaring disk model given by Chiang and Goldreich in 1997, but with the central regions of the disk
The effect of dust settling on the appearance of protoplanetary disks
We analyze how the process of dust settling affects the spectral energy distribution and optical appearance of pro- toplanetary disks. Using simple analytic estimates on the one hand, and detailed
Coagulation, fragmentation and radial motion of solid particles in protoplanetary disks
The growth of solid particles towards meter sizes in protoplanetary disks has to circumvent at least two hurdles, namely the rapid loss of material due to radial drift and particle fragmentation due
Gas- and dust evolution in protoplanetary disks
Context. Current models of the size- and radial evolution of dust in protoplanetary disks generally oversimplify either the radial evolution of the disk (by focussing at one single radius or by using
A “Starless” Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope show the presence of an embedded source. We propose a
The Disk Substructures at High Angular Resolution Project (DSHARP). I. Motivation, Sample, Calibration, and Overview
We introduce the Disk Substructures at High Angular Resolution Project (DSHARP), one of the initial Large Programs conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The primary
