The CO snow line favours strong clumping by the streaming instability in protoplanetary discs with porous grains
Jean-François Gonzalez, Stéphane Michoulier
Context: The radial drift and fragmentation of small dust grains in protoplanetary discs impedes their growth past centimetre sizes. Several mechanisms have been proposed to overco…

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…
