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…
A smoothed particle hydrodynamics algorithm for multigrain dust with separate sets of particles
Daniel Mentiplay, Daniel J. Price, Christophe Pinte +1
We present a method for simulating the dynamics of a mixture of gas and multiple species of large Stokes number dust grains, typical of evolved protoplanetary discs and debris disc…
Protostellar collapse: the conditions to form dust rich protoplanetary disks
Ugo Lebreuilly, Benoît Commerçon, Guillaume Laibe
Dust plays a key role during star, disk and planet formation. Yet, its dynamics during the protostellar collapse remains a poorly investigated field. Recent studies seem to indicat…
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…
A solution to the overdamping problem when simulating dust-gas mixtures with smoothed particle hydrodynamics
Daniel J. Price, Guillaume Laibe
We present a fix to the overdamping problem found by Laibe & Price (2012) when simulating strongly coupled dust-gas mixtures using two different sets of particles using smoothed pa…
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…
