How is angular momentum transferred outward in modern Nebular Theory refinements?

Through magnetic braking interacting with ionized gas

Early versions of the nebular hypothesis struggled to explain a critical mass distribution puzzle: how the vast majority of angular momentum remained locked in the Sun's rotation while planets formed. Modern refinements, which evolve the concept into the Nebular Theory, address this through specific physical mechanisms. The current understanding involves magnetic braking. This process occurs when the strong magnetic field lines emanating from the young, rotating Sun become entangled with the charged, ionized gas still present in the inner regions of the protoplanetary disk. This interaction effectively acts as a brake on the Sun's spin while simultaneously transferring that rotational energy (angular momentum) outward into the disk material, eventually contributing to the orbits of the forming planets.
