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 …

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 …

Context. Spiral arms, rings and large scale asymmetries are structures observed in high
resolution observations of protoplanetary disks, and it appears that some of the disks …

ABSTRACT A pathway to the formation of planetesimals, and eventually giant planets, may
occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent …

Planet–disc interactions build up local pressure maxima that may halt the radial drift of
protoplanetary dust, and pile it up in rings and crescents. ALMA observations of the HD …

The early stages of dynamical evolution of planetary systems are often shaped by
dissipative processes that drive orbital migration. In multi-planet systems, convergent …

We investigate the dynamics of large dust grains in massive lopsided transition discs via 2D
hydrodynamical simulations including both gas and dust. Our simulations adopt a ring-like …

Environmental effects, such as stellar fly-bys and external irradiation, are thought to affect
the evolution of protoplanetary discs in clustered star formation. Previous Atacama Large …

Motivated by lopsided structures observed in some massive transition discs, we have carried
out 2D numerical simulations to study vortex structure in massive discs, including the effects …

Protoplanetary disks with non-axisymmetric structures have been observed. The Rossby
wave instability (RWI) is considered as one of the origins of the non-axisymmetric structures …
