Eccentricity evolution of the planet ending up in the inner orbit after a collisional event involving two of the three initial planets. Different starting values of the planet semimajor axes are adopted. The legend within the figure gives the final semimajor axis of the inner planet when a dynamically stable configuration is reached. Different dynamical final states are illustrated. The blue line shows a regular secular evolution of the two surviving planets after the collision. The black line shows a sharp grow of the eccentricity during the chaotic evolution followed by a slow tidal damping of the inner planet, the less massive of the two. The red line shows a case where two collisions occur and a single massive planet is left on aneccentric orbit. The green line shows the case in which the merged planet ends up into a highly eccentric orbit and its evolution is decoupled from the outer planet.
