Evading the dust fragmentation barrier with the streaming instability in protoplanetary disks
V. Vallucci-Goy, U. Lebreuilly, M. -M. Mac Low +1
Context: The streaming instability (SI) is a leading candidate for reaching solid densities sufficient to trigger the gravitational collapse needed for the formation of planetesima…

Magnetic clumping of charged dust in the dense interstellar medium
V. Vallucci-Goy, P. Hennebelle, U. Lebreuilly +1
Context: Dust grains undergo significant growth in star-forming environments, especially in dense regions prone to gravitational collapse. Although dust is generally assumed to rep…

Dust evolution during the protostellar collapse: influence on the coupling between the neutral gas and the magnetic field
Valentin Vallucci-Goy, Ugo Lebreuilly, Patrick Hennebelle
The coupling between the magnetic field and the gas during the collapsing phase of star-forming cores is strongly affected by the dust size distribution, which is expected to evolv…
