Mapping the structure of the planetary 2:1 mean motion resonance. The TOI-216, K2-24, and HD27894 systems
Cristian Giuppone, Adrián Rodríguez, Viviam Alencastro +2
Mean motion resonances (MMR) are a frequent phenomenon among extrasolar planetary systems. Current observations indicate that many systems have planets that are close to or inside…
The current orbit of Atlas (SXV)
Demetrio Tadeu Ceccatto, Nelson Callegari, Adrián Rodríguez
With the success of the Cassini-Huygens mission, the dynamic complexity surrounding natural satellites of Saturn began to be elucidated. New ephemeris could be calculated with a hi…
The current orbit of Methone (S/2004 S 1)
Nelson Callegari, Adrián Rodríguez, Demétrio Tadeu Ceccatto
The Cassini spacecraft discovered many close-in small satellites in Saturnian system, and several of them exhibit exotic orbital states due to interactions with Mimas and the oblat…
Dynamical stability in the vicinity of Saturnian small moons. The cases of Aegaeon, Methone, Anthe and Pallene
Adrián Rodríguez, Nelson Callegari
In this work we analyze the orbital evolution and the dynamical stability in the vicinity of the small Saturnian moons Aegaeon, Methone, Anthe and Pallene. We numerically resolve t…
Deformation and tidal evolution of close-in planets and satellites using a Maxwell viscoelastic rheology
Alexandre C. M. Correia, Gwenaël Boué, Jacques Laskar +1
In this paper we present a new approach to tidal theory. Assuming a Maxwell viscoelastic rheology, we compute the instantaneous deformation of celestial bodies using a differential…
Tidal evolution of close-in exoplanets in co-orbital configurations
Adrián Rodríguez, Cristian A. Giuppone, Tatiana A. Michtchenko
In this paper, we study the behavior of a pair of co-orbital planets, both orbiting a central star on the same plane and undergoing tidal interactions. Our goal is to investigate f…
On the equilibrium figure of close-in planets and satellites
Alexandre C. M. Correia, Adrian Rodriguez
Many exoplanets have been observed close to their parent stars with orbital periods of a few days. As for the major satellites of the Jovian planets, the figure of these planets is…
Dynamics of Rotation of Super-Earths
Nelson Callegari, Adrian Rodríguez
We numerically investigate the dynamics of rotation of several close-in terrestrial exoplanet candidates. In our model, the rotation of the planet is disturbed by the torque of the…
Angular momentum exchange during secular migration of two-planet systems
Adrián Rodríguez, Tatiana A. Michtchenko, Octavio Miloni
We investigate the secular dynamics of two-planet coplanar systems evolving under mutual gravitational interactions and dissipative forces. We consider two mechanisms responsible f…
On planetary mass determination in the case of super-Earths orbiting active stars. The case of the CoRoT-7 system
S. Ferraz-Mello, M. Tadeu dos Santos, C. Beauge +2
This investigation uses the excellent HARPS radial velocity measurements of CoRoT-7 to re-determine the planet masses and to explore techniques able to determine mass and elements…
Tidal decay and circularization of the orbits of short-period planets
Adrian Rodriguez, Sylvio Ferraz-Mello
We analyze the long-term tidal evolution of a single-planet system through the use of numerical simulations and averaged equations giving the variations of semi-major axis and ecce…
Tidal friction in close-in satellites and exoplanets. The Darwin theory re-visited
Sylvio Ferraz-Mello, Adrián Rodríguez, Hauke Hussmann
This report is a review of Darwin's classical theory of bodily tides in which we present the analytical expressions for the orbital and rotational evolution of the bodies and for t…
