Star formation in a dusty plasma cloud

A dusty plasma cloud in space has a gravitational instability which allows star formation even orders of magnitude below the Jeans limit for gravitational collapse. This instability leads to a stellesimal accretion which is analogous to the planetesimal accretion. If the law of sochronism which holds for planetesimal accretion. If the law of isochronism which holds for planetesimal accretion is applied to the formation of our sun, it gives an acceptable angular momentum to the early sun. Furthermore, the situation in the solar environment is reconcilable with the initial condition for formation of planets. (author)
