Magnetohydrodynamics of charged interstellar dust. Multifluid models and study of the linear modes
Gabriel Verrier, Patrick Hennebelle, Ugo Lebreuilly +1
Interstellar grains play key roles in star and planet formation, including the coupling of the gas to the magnetic field during the protostellar collapse. These roles depend on the…
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…
Protostellar collapse simulations in spherical geometry with dust coagulation and fragmentation
Ugo Lebreuilly, Valentin Vallucci-Goy, Vincent Guillet +2
We model the coagulation and fragmentation of dust grains during the protostellar collapse with our newly developed shark code. It solves the gas-dust hydrodynamics in a spherical…
