Scientific paper

The process of star formation from a hot cloud with a magnetic field of about 3 microG is discussed. A simplified model of initial collapse is used to define a critical mass (Mc) range within which the interaction of gravitational and magnetic forces is complex. The collapsed-disk model of Mestel and Ray (1983) is examined, and the effects of angular momentum are analyzed for disks with masses somewhat greater and somewhat smaller than Mc. It is suggested that a protocometary cloud (with high angular momentum and M greater than Mc) and a protosolar cloud (with low angular momentum and M less than Mc) may have arisen from the fragmentation of one larger cloud.
