The problem discussed is the following What happens to the orbital eccentricity of a particle in orbit around a body that is accumulating mass by accretion. This question occurred to the writer in connection with studies on the origin of planetary systems. It was concluded, from a computer analysis, that the orbital eccentricity of a particle in orbit around a gradually growing mass does not change significantly with time. Thus the observed low orbital eccentricities in the solar system, assuming the above conclusion can be applied to multibody systems, must result from some other mechanism.
