While it has been shown that magnetic fields are theoretically able to significantly contribute to solving the
angular momentum problem for star formation, the physics at work to conserve or dissipate angular momentum during
the main accretion phase – and therefore the processes allowing star, disk and planet formation – is still
surprisingly poorly understood. The exact role of magnetic braking in regulating angular momentum during the
early phases of star formation still has to be addressed observationally.
The MagneticYSOs project aims at testing
if magnetic fields are the missing piece allowing to solve the angular momentum problem during the Class 0 phase.
This major leap forward is made possible by our novel approach combining unprecedented detailed analysis of a complete
set of observational constraints, and their confrontation to comprehensive MHD simulations of protostellar collapse.
