Abstract

Extrasolar planets in multiple star systems, considered nowadays as a common phenomenon in the universe, is still a subject that challenges the classical theories by their orbital characteristics very different from Solar System's planets. In this project we intend to apply new techniques, analytical and semi-analytical, to build dynamic models of these systems, based on successful applications of such techniques for the study of the secular planetary problem at (Michtchenko and Malhotra 2004).
