The objective of this project is to study the evolution of planets which are close to their host stars (hot Jupiters and super-earths), the host stars of planetary systems and the major planetary satellites of the solar system. In all such cases, the evolution is dictated by the tides dynamics, which causes effects on the rotational movement of these bodies that depend on their composition and how they respond to internal strain. In addition, the knowledge of the orbital and rotational evolution offers information about the past and the future of the systems to which these bodies belong. For the development of the project, the Newtonian creep theory developed by Sylvio Ferraz-Mello and later extended by Hugo A. Folonier to a multilayered body will be used. (AU)
