The formation of planetesimals, the kilometer-sized planetary precursors, is still a puzzling
process. Considerable progress has been made over the past years in the physical …

Flattened, rotating disks of cool dust and gas extending for tens to hundreds of astronomical
units are found around almost all low-mass stars shortly after their birth. These disks …

Rings are the most frequently revealed substructure in Atacama Large Millimeter/
submillimeter Array (ALMA) dust observations of protoplanetary disks, but their origin is still …

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 …

We present the results of a high angular resolution (0 farcs 3≈ 40 AU) Submillimeter Array
survey of the 345 GHz (870 μm) thermal continuum emission from nine of the brightest, and …

By carrying out two-dimensional two-fluid global simulations, we have studied the response
of dust to gap formation by a single planet in the gaseous component of a protoplanetary …

Aims. Photodissociation by UV light is an important destruction mechanism for carbon
monoxide (CO) in many astrophysical environments, ranging from interstellar clouds to …

We present new results from a significant extension of our previous high angular resolution
(0 farcs 3≈ 40 AU) submillimeter array survey of the 340 GHz (880 μm) thermal continuum …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …

We present a combined, homogenized analysis of archival Submillimeter Array (SMA) and
Atacama Large Millimeter/submillimeter Array (ALMA) observations of the spatially resolved …
