The Structure and Evolution of Protoplanetary Disks: an infrared and submillimeter view

, 2015
Circumstellar disks are the sites of planet formation, and the very high incidence of extrasolar planets implies that most of them actually form planetary systems.

Physical Processes in Protoplanetary Disks [PDF]

, 2019
This review introduces physical processes in protoplanetary disks relevant to accretion and the initial stages of planet formation. After a brief overview of the observational context, I introduce the elementary theory of disk structure and evolution, review the gas-phase physics of angular momentum transport through turbulence and disk winds, and ...

Dust crystallinity in protoplanetary disks: the effect of diffusion/viscosity ratio

, 2007
The process of turbulent radial mixing in protoplanetary disks has strong relevance to the analysis of the spatial distribution of crystalline dust species in disks around young stars and to studies of the composition of meteorites and comets in our own ...

Carbon In Protoplanetary Disks

, 2018
The carbon and oxygen content of the solids in protoplanetary disks plays an important role in defining the composition of giant planet atmospheres. I will discuss what we know about the distribution of carbonaceous material in the solar system and discuss potential processes influencing its radial distribution. I will also present modeling results for

Measuring the Two-dimensional Thermal Structures of Protoplanetary Disks

The Astrophysical Journal
We present a flexible, annulus-by-annulus method to constrain the 2D thermal structure of a protoplanetary disk from optically thick spectral line emission.

Dust growth in protoplanetary disks - a comprehensive experimental/theoretical approach

, 2010
More than a decade of dedicated experimental work on the collisional physics of protoplanetary dust has brought us to a point at which the growth of dust aggregates can - for the first time - be self-consistently and reliably modelled.

JVLA Measurement of Grain Size in the Compact Dust Ring Around Class I Protostar WL 17

The Astronomical Journal
The maximum grain size in protoplanetary disks is a critical parameter for planet formation, as the efficiency of mechanisms like streaming instability and pebble accretion depend on grain size.

Dust Ejection from Planetary Bodies by Temperature Gradients: Laboratory Experiments

, 2011
Laboratory experiments show that dusty bodies in a gaseous environment eject dust particles if they are illuminated. We find that even more intense dust eruptions occur when the light source is turned off.

exoALMA. I. Science Goals, Project Design, and Data Products

The Astrophysical Journal Letters
Planet formation is a hugely dynamic process requiring the transport, concentration, and assimilation of gas and dust to form the first planetesimals and cores.
