| Abstract: | Summary It is proposed that gravitational torques can furnish a mechanism for the radial outward transport of angular momentum in the solar nebula. For this effect to be present the disc of the nebula must have a spiral structure with trailing arms. A mathematical model is constructed with the main object of seeing whether purely advective inward eddy transports of angular momentum could offset the gravitational torques. It is found that for a protosun much more massive than the disc the eddy transport is small, allowing the gravitational effects of predominate. In such a case convergence of angular momentum is to be expected at the outer edge of the disc. The possibility exists that matter could be shed to large distances perhaps giving rise to the cloud of comets surrounding the solar system as proposed byJ. H. Oort. |
