| description | A planet revolving around binary star system is a familiar system. Studies of these systems are important because they
provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution
of an exoplanet revolving around a binary star system using different rates of stellar mass loss will be introduced. Using
a hierarchical triple body system, in which the outer body can be moved with the center of mass of the inner binary star
as a two-body problem, the long period evolution of the exoplanet orbit is determined depending on a Hamiltonian
formulation. The model is simulated by numerical integrations of the Hamiltonian equations for the system over a long
time. As a conclusion, the behavior of the planet orbital elements is quite affected by the rate of the mass loss from the
accompanying binary star. |
