DESCRIPTION:Speakers: Pierre Marchand (American Museum of Natural History)
 \nMagnetic fields play a major role in the regulation of angular momentum 
 during the protostellar collapse\, hence for the formation of the protopla
 netary disk. The magnetic braking is able to slow the rotation and extract
  the angular momentum from the disk. However\, this process is tampered by
  a decoupling between neutral and charged particles\, especially the ions 
 through the ambipolar diffusion. The decoupling is heavily impacted by the
  chemistry at stake\, and particularly by the grain size distribution. I w
 ill show how a modification of the grain size distribution enhances the de
 coupling between the magnetic field and the gas\, and how it modifies the 
 distribution and transport of angular momentum.\n\nhttps://iaus379.aip.de/
