The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

A large fraction of the protoplanetary disks observed with ALMA display multiple well-
defined and nearly perfectly circular rings in the continuum, in many cases with substantial …

Context. The global size and spatial distribution of dust is an important ingredient in the
structure and evolution of protoplanetary disks and in the formation of larger bodies, such as …

Turbulence is a fundamental parameter in models of grain growth during the early stages of
planet formation. As such, observational constraints on its magnitude are crucial. Here we …

Turbulence can transport angular momentum in protoplanetary disks and influence the
growth and evolution of planets. With spatially and spectrally resolved molecular emission …

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 …

Protoplanetary disks are quasi-steady structures whose evolution and dispersal determine
the environment for planet formation. I review the theory of protoplanetary disk evolution and …

Accumulation of dust and ice particles into planetesimals is an important step in the planet
formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores …

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. We attempt to explain grain growth to mm sized particles and their retention in the
outer regions of protoplanetary disks, as observed at sub-mm and mm wavelengths, by …
