Invited Presentation
Magnetically regulated collapse in the B335 protostar ? ALMA observations and MHD models
Presenter: Anaëlle Maury (CEA Astrophysics department, Paris-Saclay University)
Recent observational and theoretical results highlight the role of magnetic braking for several long-standing problems in astronomy such as the angular momentum problem, and the formation of stellar binaries and disks.
We carried out an SMA survey of the polarized dust emission in a sample of low-mass Class 0 protostars, which main results I will present. I will then focus on the B335 protostar for which we obtained follow-up ALMA observations. We have confronted our observational constraints in B335 with realistic outputs from non-ideal MHD simulations of core collapse.
I will present our first results attempting to characterize the magnetic field roles in this young protostar, using ALMA observations and MHD simulations.
