A planetesimal moving in the Solar Nebula experiences an aerodynamic drag which causes its orbit to circularize and shrink. However, resonant perturbations from a protoplanet interior to the planetesimal's orbit can counteract both the orbital decay and the damping of the eccentricity: the planetesi

We consider the problem of the orbital evolution of solid particles in a gas-rich planetary nebula where one planetary embryo already exists (Weidenschilling and Davis model). The case of a Stokes drag is studied both analytically and numerically. We present the equations of the averaged model for t
