Capture of small meter-to-km planetesimals in MMR by a 2 Earth mass planet
Description: Size dependence and librational eccentricity for capture in MMR of small planetesimals drifting within a gaseous environment as a function of the semimajor axis. The large black circle represents a 2 Earth mass planet. Small open circles represent planetesimals of different sizes (s = [0.01-10] km). The curved line in the top panel stands for the librational eccentricities. The vertical dashed lines show all first order MMRs from 20:10 to 11:10 (gray) and from 10:9 to 3:2 (black).
