    The spin–orbit resonant problem including core–mantle gravitational coupling

    In this work, we numerically study an improved model of the spin–orbit resonances with applications in the exoplanetary dynamics. While in the classical model the planetary rotation is characterized by the mot...

    Dynamics of Enceladus and Dione inside the 2:1 mean-motion resonance under tidal dissipation

    In a previous work (Callegari and Yokoyama, Celest. Mech. Dyn. Astr. 98:5–30, 2007), the main features of the motion of the pair Enceladus–Dione were analyzed in the frozen regime, i.e., without considering th...

    Dynamics of two satellites in the 2/1 Mean–Motion resonance: application to the case of Enceladus and Dione

    The dynamics of a pair of satellites similar to Enceladus–Dione is investigated with a two-degrees-of-freedom model written in the domain of the planar general three-body problem. Using surfaces of section and...

    Dynamics of Two Planets in the 3/2 Mean-motion Resonance: Application to the Planetary System of the Pulsar PSR B1257+12

    This paper considers the dynamics of two planets, as the planets B and C of the pulsar PSR B1257+12, near a 3/2 mean-motion resonance. A two-degrees-of-freedom model, in the framework of the general three-body...

    Dynamics of Two Planets in the 2/1 Mean-Motion Resonance

    The dynamics of two planets near a first-order mean-motion resonance is modeled in the domain of the general three-body planar problem. The system studied is the pair Uranus-Neptune (2/1 resonance). The phase ...

    Dynamics of Fictitious Earth’s Satellites with Possible Past Values of the Ecliptic

    According to many authors, there is no reason to believe that inner planets never had satellites in the past. Indeed, (1972), (1973), (1973), etc, explain their disappearance using essentially tidal effects which...
