Collapse and Fragmentation of Rotating Magnetized Clouds. I. Magnetic Flux - Spin Relation

We discuss the evolution of the magnetic flux density and angular velocity in a molecular cloud core, on the basis of three-dimensional numerical simulations, in which a rotating magnetized cloud fragments and collapses to form a very dense optically thick core of >5 × 1010 cm−3. As the density increases towards the formation of the optic...更多
