Sintering-induced dust ring formation in protoplanetary disks: Application to the HL tau disk
The latest observation of HL Tau by ALMA revealed spectacular concentric dust rings in its
circumstellar disk. We attempt to explain the multiple ring structure as a consequence of …

Global simulations of protoplanetary disks with net magnetic flux-i. non-ideal mhd case
W Béthune, G Lesur, J Ferreira - Astronomy & Astrophysics, 2017 - aanda.org
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 …

Efficient planet formation by pebble accretion in ALMA rings
H Jiang, CW Ormel - Monthly Notices of the Royal Astronomical …, 2023 - academic.oup.com
In the past decade, ALMA observations have revealed that a large fraction of protoplanetary
discs contains rings in the dust continuum. These rings are the locations where pebbles …

One solution to the mass budget problem for planet formation: optically thick disks with dust scattering
Abstract Atacama Large Millimeter Array (ALMA) surveys have suggested that the dust in
Class II disks may not be enough to explain the averaged solid mass in exoplanets, under …
