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…
How magnetic field and stellar radiative feedback influences the collapse and the stellar mass spectrum of a massive star forming clump
Patrick Hennebelle, Ugo Lebreuilly, Tine Colman +10
In spite of decades of theoretical efforts, the physical origin of the stellar initial mass function (IMF) is still debated. We aim at understanding the influence of various physic…
Chemical Diversity in Protoplanetary Disks and Its Impact on the Formation History of Giant Planets
Elenia Pacetti, Diego Turrini, Eugenio Schisano +7
Giant planets can interact with multiple and chemically diverse environments in protoplanetary discs while they form and migrate to their final orbits. The way this interaction aff…
Fast methods to track grain coagulation and ionization. II. Extension to thermal ionization
Pierre Marchand, Vincent Guillet, Ugo Lebreuilly +1
Thermal ionization is a critical process at temperatures T > 10 3 K, particularly during star formation. An increase in ionization leads to a decrease in nonideal magnetohydrodynam…
