A Possible Correlation between the Gaseous Drag Strength and Resonant Planetesimals in Planetary Systems

Abstract

We study the migration and resonant capture of planetesimals in a planetary system consisting of a gaseous disc analogous to the primordial solar nebula and a Neptune-like planet. Using a simple treatment of the drag force we find that planetesimals are mainly trapped in the 3:2 and 2:1 resonances and that the resonant populations are correlated with the… (More)
