DESCRIPTION:Using the correspondence limit of Nelson's Stochastic mechanic
 s for the atomic elliptic state in a Coulomb potential\, we find stationar
 y state solutions of a related Burgers equation in which the Burgers fluid
  is\nattracted to a Keplerian elliptical orbit in the infinite time limit.
   Modelling collisions between the Nelsonian particles making up the fluid
  and Newtonian planetesimals by classical mechanics leads to a Burgers-Zel
 dovich equation with vorticity. Here planetesimals are forced to spin abou
 t the axis normal to the plane of motion and their masses obey an arcsine 
 law for elliptical orbits of small eccentricity. A preliminary study of th
 e Stochastic Burgers-Zeldovich equation will be presented.
