Which mechanism attempts to resolve the angular momentum imbalance in the Solar System?

Answer

Magnetic braking via solar wind interaction.

The protoplanet hypothesis inherits the significant Angular Momentum Problem from earlier nebular theories. This problem centers on the observed mass distribution of the Solar System: the Sun contains approximately 99% of the total mass, yet the orbiting planets collectively hold about 99% of the total angular momentum. This distribution implies that the star must have spun down considerably during formation. The proposed correction mechanism for transferring angular momentum outward from the spinning Sun to the surrounding disk material (which eventually forms the planets) is magnetic braking. This process involves the interaction between the star's magnetic field and the charged particles of the solar wind, effectively slowing the star's rotation.
