The authors discuss the physics of magnetic field dissipation and reconnection during protostellar formation. In their analysis of quasi-equilibrium collapse they have incorporated both ambipolar diffusion and magnetic dissipation processes. Both the final flux and angular momentum problems can be resolved in their model which incorporates some of the detailed physics that was previously lacking in such theories. The energy input during flux destruction is considerable and the authors have speculated that consequences may include the formation of a hot corona with an observable X-ray flux, and the pumping of OH masers. Radio emission may be observable in this phase.
