Variations in the semimajor axis of a planetary orbit during the accumulation process
Abstract
The magnitude of the regular shift of the semimajor axis of a planetary orbit from its initial value is evaluated as well as that of the root mean square deviation due to interactions with the cluster's bodies. It is shown that the former value is small in comparison with the latter. The root mean square deviation for the earth is in the 0.01-0.3 AU range depending on the ratio of the average mass of the bodies in the cluster to the mass of the accumulating planet. The results are of interest in connection with accumulation processes in the preplanetary swarm in the primordial solar system.
