Abstract

The aim of this project is a study of the dynamical evolution of two exoplanets in co-orbital motion, which orbit the central star with periods of a few days. The model developed accounts for tidal effects with the central star, together with mutual planetary perturbations. Applying the model we simulate the long-term behavior of the Trojan-like bodies under dissipation. (AU)
