Effects of Chaotic Clearing in Planetary Systems

Abstract

In this Chapter, major types of chaotic clearing effects in planetary systems and their subsystems are considered. Generally, the clearing effects consist in forming orbital zones free from low-mass material (e.g., planetesimals, asteroids, particles, fragments), due to the dynamical chaotization in presence of perturbations. The following clearing effects are known and wellstudied: the close-to-coorbital clearing, circumbinary clearing, circumnuclear clearing, inner disintegration. Analytical approaches that serve to characterize these effects, in particular, serve for estimating the cleared zone sizes and the clearing timescales, are described and discussed.
