As planets form and grow within gaseous protoplanetary disks, the mutual gravitational
interaction between the disk and planet leads to the exchange of angular momentum and …

We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

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 an efficient and simple modification of the standard transport algorithm used in
explicit eulerian fixed polar grid codes, aimed at getting rid of the average azimuthal velocity …

Protoplanetary disks dissipate rapidly after the central star forms, on time-scales comparable
to those inferred for planet formation. In order to allow the formation of planets, disks must …

We study the torque on low-mass planets embedded in protoplanetary discs in the two-
dimensional approximation, incorporating non-isothermal effects. We couple linear …

In this paper we present the global baroclinic instability as a source for vigorous turbulence
leading to angular momentum transport in Keplerian accretion disks. We show by analytical …

We perform numerical simulations of a disc–planet system using various grid-based and
smoothed particle hydrodynamics (SPH) codes. The tests are run for a simple setup where …

We analyze the nonlinear, two-dimensional response of a gaseous, viscous protoplanetary
disk to the presence of a planet of one Jupiter mass (1 MJ) and greater that orbits a 1 M☉ …

Direct imaging observations have revealed spiral structures in protoplanetary disks.
Previous studies have suggested that planet-induced spiral arms cannot explain some of …
