Compaction during fragmentation and bouncing produces realistic dust grain porosities in protoplanetary discs
Stéphane Michoulier, Jean-François Gonzalez, Daniel J. Price
Context: In protoplanetary discs, micron-sized dust grows to form millimetre- to centimetre-sized pebbles but encounters several barriers during its evolution. Collisional fragment…
Aeolian erosion in protoplanetary discs: How impactful it is on dust evolution?
Stéphane Michoulier, Jean-François Gonzalez, Evgeni Grishin +1
Context: Many barriers prevent dust to form planetesimals via coagulation in protoplanetary discs, such as bouncing, collisional fragmentation or aeolian erosion. Modelling dust an…
Dynamical detection of a companion driving a spiral arm in a protoplanetary disk
Chen Xie, Bin B. Ren, Ruobing Dong +6
Radio and near-infrared observations have observed dozens of protoplanetary disks that host spiral arm features. Numerical simulations have shown that companions may excite spiral…
Dust grain shattering in protoplanetary discs: collisional fragmentation or rotational disruption?
Stéphane Michoulier, Jean-François Gonzalez
In protoplanetary discs, the coagulation of dust grains into large aggregates still remains poorly understood. Grain porosity appears to be a promising solution to allow the grains…
The Origin of the Doppler-flip in HD 100546: a large scale spiral arm generated by an inner binary companion
Brodie J. Norfolk, Christophe Pinte, Josh Calcino +9
Companions at sub-arcsecond separation from young stars are difficult to image. However their presence can be inferred from the perturbations they create in the dust and gas of pro…
Dust Traffic Jams in Inclined Circumbinary Protoplanetary Discs I. Morphology and Formation Theory
Hossam Aly, Jean-François Gonzalez, Rebecca Nealon +3
Gas and dust in inclined orbits around binaries experience precession induced by the binary gravitational torque. The difference in precession between gas and dust alters the radia…
