Estabilidad orbital de planetas no coplanares en un sistema estelar binario

Abstract

Since few years ago, it has been suggested the search of circumbinary planets in an orbit with very high inclination, relative of binary system planet. If these orbits are very stable, probably most of circumbinary system could be like that. In this work, we have studied stability of different circumbinary planets orbits with inclination i_pl = 60° , relative of binary system plane. The investigation of stability was carried out through simulations with a N-body integration code, doing simulations of circumbinary system with a planet mass of m_pl = 10⁻⁵ M_☉ and binary system with two stars of mass m₁ = m₂ = 0.5 M_☉. We made a full of 1174 numerical simulations of the cirumbinary planets orbits, changing relative distance (κ) beetwen binary sistem and circumbinary planet orbits. We found the orbital critical stability κ_crit = 1.955  and some resonances of the planet orbit, in which we found inestability or high changes of planet excentricity.
