Dust Growth in Binary Systems: Inhibition of dust settling and growth in circumbinary discs
Antoine Alaguero, Nicolás Cuello, Jean-François Gonzalez +4
Stellar multiplicity alters the density structure of protoplanetary discs and thereby the initial conditions for planet formation. Yet, the interplay between companion-disc interac…
Full one-fluid dusty gas with multiple grain species in SPH
Mark Hutchison, Guillaume Laibe, Giovanni Tedeschi-Prades +5
We present a Smoothed Particle Hydrodynamics (SPH) implementation of the full one-fluid dusty gas algorithm for multiple dust species, generalising our previous terminal velocity a…
On the 3D time evolution of the dust size distribution in protostellar envelopes
Maxime Lombart, Ugo Lebreuilly, Anaëlle Maury
Dust plays a fundamental role during protostellar collapse, disk and planet formation. Recent observations suggest that efficient dust growth may begin early, in the protostellar e…
General non-linear fragmentation with discontinuous Galerkin methods
Maxime Lombart, Charles-Edouard Bréhier, Mark Hutchison +1
Dust grains play a significant role in several astrophysical processes, including gas/dust dynamics, chemical reactions, and radiative transfer. Replenishment of small-grain popula…
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…
Fragmentation with Discontinuous Galerkin schemes: Non-linear fragmentation
Maxime Lombart, Mark Hutchison, Yueh-Ning Lee
Small grains play an essential role in astrophysical processes such as chemistry, radiative transfer, gas/dust dynamics. The population of small grains is mainly maintained by the…
On the Courant-Friedrichs-Lewy condition for numerical solvers of the coagulation equation
G. Laibe, M. Lombart
Evolving the size distribution of solid aggregates challenges simulations of young stellar objects. Among other difficulties, generic formulae for stability conditions of explicit…
New binaries from the SHINE survey
M. Bonavita, R. Gratton, S. Desidera +67
We present the multiple stellar systems observed within the SpHere INfrared survey for Exoplanet (SHINE). SHINE searched for substellar companions to young stars using high contras…
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…
