Recent developments in the analytic modelling of polar and retrograde asteroids in resonance with the giant planets orbital frequencies allowed the identification of the first examples of these configurations in the solar system. In this project we will analyze the possibility of occurance of these type of resonances between extrasolar planets and also between satellites. We will also stu…
The existence of asteroids like the coorbital 2015BZ509 and the transneptunians Niku and Drac whose orbits have high relative inclination with respect to the planets' orbital plane is problematic in the context of the current theories for formation and evolution of the solar system. The recent modelling and subsequent identification of orbital resonances with the giant planets was ess…

Extrasolar systems may have planets with inclined orbits, prograde or retrograde. In this project we will study formation mechanisms of extrasolar systems with planets in orbits with high relative inclinations. We will analyse the evolution of these systems due to dissipative effects, in particular capture and stability of resonant configurations.
Recent theoretical developments allowed the identification of small bodies in retrograde resonances with the Solar System planets. Retrograde resonances are also possible in extrasolar systems, in particular, for planets in stellar binary systems. In this project we will obtain the families of periodic orbits associated with retrograde resonances in stellar binary systems, and we will an…
Recent theoretical developments led to the identification of small bodies in retrograde resonances with the solar system planets. However, extra solar systems could have planets in retrograde configurations. In this study we will study the stability, viability and detectability of these extra solar systems.
Recently, the existence of retrograde coorbital configurations in the solar system has been confirmed: asteroid (514107) Ka'epaoka'awela that revolves around the sun in the same period as Jupiter but orbiting in the opposite direction. Simulations of the 3-body problem with dissipation showed that retrograde resonances, and particularly the coorbital resonance, capture objects more effici…
Recent theoretical developments led to the identification of small bodies in retrograde resonances with Solar System planets. However, extrasolar systems may also have planets in retrograde resonant configurations. In the master of science project with grant FAPESP/2021/11982-5 we are studying the stability, viability and detectability of these extrasolar systems. In the proposed BEPE pro…
