Radiation Magnetohydrodynamics In Global Simulations Of Protoplanetary Disks
M. Flock, S. Fromang, M. González +1
Our aim is to study the thermal and dynamical evolution of protoplanetary disks in global simulations, including the physics of radiation transfer and magneto-hydrodynamic (MHD) tu…
Simulating gamma-ray binaries with a relativistic extension of RAMSES
Astrid Lamberts, Sebastien Fromang, Guillaume Dubus +1
Gamma-ray binaries are composed of a massive star and a rotation-powered pulsar with a highly relativistic wind. The collision between the winds from both objects creates a shock s…
MRI-driven angular momentum transport in protoplanetary disks
Sebastien Fromang
Angular momentum transport in accretion disk has been the focus of intense research in theoretical astrophysics for many decades. In the past twenty years, MHD turbulence driven by…
The influence of turbulence during magnetized core collapse and its consequences on low-mass star formation
Marc Joos, Patrick Hennebelle, Andrea Ciardi +1
[Abridged] Theoretical and numerical studies of star formation have shown that magnetic field (B) has a strong influence on both disk formation and fragmentation; even a relatively…
