This review addresses the state of research that employs astronomical (remote sensing)
observations of solids (“dust”) in young circumstellar disks to learn about planet formation …

We present the first high-resolution sub-millimeter survey of both dust and gas for a large
population of protoplanetary disks. Characterizing fundamental properties of protoplanetary …

Spatially resolved structures in protoplanetary disks hint at unseen planets. Previous
imaging observations of the transitional disk around MWC 758 revealed an inner cavity, a …

High spatial resolution CO observations of midinclination (≈ 30–75) protoplanetary disks
offer an opportunity to study the vertical distribution of CO emission and temperature. The …

Context. Transitional disks with large dust cavities are important laboratories in which to
study planet formation and disk evolution. Cold gas may still be present inside these …

Transition disks with large dust cavities around young stars are promising targets for
studying planet formation. Previous studies have revealed the presence of gas cavities …

Context. Transitional disks around young stars with large dust cavities are promising
candidates to look for recently formed, embedded planets. Models of planet-disk interaction …

High-spatial-resolution observations of CO isotopologue line emission in protoplanetary
disks at mid-inclinations (≈ 30–75) allow us to characterize the gas structure in detail …

Context. Gaps, cavities, and rings in circumstellar disks are signposts of disk evolution and
planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with a …

We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars
from 11 star-forming regions, ranging from∼ 0.5 to 10 Myr old. The disk masses we infer …
