Star formation is a multi-scale, multi-physics problem ranging from the size scale of
molecular clouds (∼ 10 ∼10 s pc) down to the size scales of dense prestellar cores (∼ 0.1 …

The theory and numerical modelling of radiation processes and radiative transfer play a key
role in astrophysics: they provide the link between the physical properties of an object and …

The enormous radiative and mechanical luminosities of massive stars impact a vast range of
scales and processes, from the reionization of the universe, to the evolution of galaxies, to …

The transport of angular momentum by magnetic fields is a crucial physical process in the
formation and evolution of stars and disks. Because the ionization degree in star-forming …

We present a new implementation of radiation hydrodynamics (RHD) in the adaptive mesh
refinement (AMR) code ramses. The multigroup radiative transfer (RT) is performed on the …

We describe and test an updated version of radiation-hydrodynamics in the ramses code,
that includes three new features:(i) radiation pressure on gas,(ii) accurate treatment of …

A large fraction of giant planets have gaseous envelopes that are limited to about 10% of
their total mass budget. Such planets are present in the solar system (Uranus, Neptune) and …

We report the first three-dimensional radiation magnetohydrodynamic (RMHD) simulations
of protostellar collapse with and without Ohmic dissipation. We take into account many …

We report the results of radiation-magnetohydrodynamics calculations in the context of high-
mass star formation, using for the first time a self-consistent model for photon emission (ie …
