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…
Fast methods for tracking grain coagulation and ionization. I. Analytic derivation
Pierre Marchand, Vincent Guillet, Ugo Lebreuilly +1
Dust grains play a major role in many astrophysical contexts. They affect the chemical, magnetic, dynamical, and optical properties of their environment, from galaxies down to the…
Dust coagulation feedback on magnetohydrodynamic resistivities in protostellar collapse
V. Guillet, P. Hennebelle, G. Pineau des Forêts +3
The degree of coupling between the gas and the magnetic field during the collapse of a core and the subsequent formation of a disk depends on the assumed dust size distribution. We…
A chemical solver to compute molecule and grain abundances and non-ideal MHD resistivities in prestellar core collapse calculations
Pierre Marchand, Jacques Masson, Gilles Chabrier +3
We develop a detailed chemical network relevant to the conditions characteristic of prestellar core collapse. We solve the system of time-dependent differential equations to calcul…
