The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

Since the discovery of the first extrasolar planet around a solartype star, 1 more than 900
such planets outside of our solar system have been detected by ground-and space-based …

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

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 …

Context. The planet-forming region of protoplanetary disks is cold, dense, and therefore
weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be …

We perform three-dimensional, vertically-stratified, local shearing-box ideal MHD
simulations of the magnetorotational instability (MRI) that include a net vertical magnetic flux …

Planets appear to form in environments shaped by the gas flowing through protostellar disks
to the central young stars. The flows in turn are governed by orbital angular momentum …

We report results from global ideal MHD simulations that study thin accretion disks (with
thermal scale height H/R= 0.1 and 0.05) threaded by net vertical magnetic fields. Our …

The structure and evolution of protoplanetary discs (PPDs) are largely governed by disc
angular momentum transport, mediated by magnetic fields. In the most observable outer …
