Formation of low mass protostars and their circumstellar disks
Adnan Ali Ahmad, Matthias González, Patrick Hennebelle +1
The birth process of circumstellar disks remains poorly constrained due to observational and numerical challenges. Recent numerical works have shown that the small-scale physics, o…
Synthetic populations of protoplanetary disks. Impact of magnetic fields and radiative transfer
U. Lebreuilly, P. Hennebelle, T. Colman +10
Protostellar disks are the product of angular momentum conservation during the protostellar collapse. Understanding their formation is crucial because they are the birthplace of pl…
The birth and early evolution of a low mass protostar
Adnan Ali Ahmad, Matthias González, Patrick Hennebelle +1
Understanding the collapse of dense molecular cloud cores to stellar densities and the subsequent evolution of the protostar is of importance to model the feedback effects such an…
Influence of protostellar outflows on star and protoplanetary disk formation in a massive star-forming clump
U. Lebreuilly, P. Hennebelle, A. Maury +5
Context. Due to the presence of magnetic fields, protostellar jets/outflows are a natural consequence of accretion onto protostars. They are expected to play an important role for…
The role of magnetic fields in the formation of multiple massive stars
R. Mignon-Risse, M. González, B. Commerçon
(Abridged) Context. Most massive stars are located in multiple stellar systems. Magnetic fields are believed to be essential in the accretion and ejection processes around single m…
Collapse of turbulent massive cores with ambipolar diffusion and hybrid radiative transfer II. Outflows
R. Mignon-Risse, M. González, B. Commerçon
(Abridged) Most massive protostars exhibit bipolar outflows. Nonetheless, there is no consensus regarding the mechanism at the origin of these outflows, nor on the cause of the les…
Discs and outflows in the early phases of massive star formation: influence of magnetic fields and ambipolar diffusion
Benoît Commerçon, Matthias González, Raphaël Mignon-Risse +2
We study mass accretion and ejection in the vicinity of massive star forming cores using high-resolution (5 au) 3D AMR numerical simulations. We investigate the mechanisms at the o…
