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…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
Grain growth for astrophysics with Discontinuous Galerkin schemes
M. Lombart, G. Laibe
Depending on their sizes, dust grains store more or less charges, catalyse more or less chemical reactions, intercept more or less photons and stick more or less efficiently to for…
VLT/SPHERE survey for exoplanets around young, early-type stars including systems with multi-belt architectures
M. Lombart, G. Chauvin, P. Rojo +21
Dusty debris disks around pre- and main-sequence stars are potential signposts for the existence of planetesimals and exoplanets. Giant planet formation is therefore expected to pl…
On the settling of small grains in dusty discs: analysis and formulas
Guillaume Laibe, Charles-Edouard Brehier, Maxime Lombart
Instruments achieve sharper and finer observations of micron-in-size dust grains in the top layers of young stellar discs. To provide accurate models, we revisit the theory of dust…
