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…

Secular evolution of resonant small bodies: semi-analytical approach for arbitrary eccentricities in the coplanar case

Juan Pons, Tabaré Gallardo

We study the secular evolution of a particle in deep mean motion resonance (MMR) with a planet in the planar elliptic restricted three body problem. We do not consider any restrict…

Semi-analytical model for planetary resonances: application to planets around single and binary stars

Tabaré Gallardo, Cristián Beaugé, Cristian A. Giuppone

In spite of planetary resonances being a common dynamical mechanism acting on planetary systems, no general model exists for describing their properties, particularly for commensur…

Three dimensional structure of mean motion resonances beyond Neptune

Tabare Gallardo

We propose a semianalytical method for the calculation of widths, libration centers and small amplitude libration periods of the mean motion resonances k_p:k in the framework of th…

Orbital stability in the Solar System for arbitrary inclinations and eccentricities: planetary perturbations versus resonances

Tabare Gallardo

Applying the technique of dynamical maps we study the orbital stability of test particles in the Solar System in the space (a,e,i) defined by 0.1<a<38 au, 0<e<0.9 and 0<i<180 ident…

The dynamical evolution of escaped Jupiter Trojan asteroids, link to other minor body populations

Romina P. Di Sisto, Ximena S. Ramos, Tabaré Gallardo

Jupiter Trojan asteroids are located around L4 and L5 Lagrangian points on relatively stable orbits, in 1:1 MMR with Jupiter. However, not all of them lie in orbits that remain sta…

Strength, stability and three dimensional structure of mean motion resonances in the Solar System

Tabare Gallardo

In the framework of the circular restricted three body problem we show that the numerically computed strength SR(e,i,w) is a good indicator of the strength and width of the mean-mo…

Co-orbital resonance with a migrating proto-giant planet

Pablo Lemos, Tabaré Gallardo

In this work we pose the possibility that, at an early stage, the migration of a proto--giant planet caused by the presence of a gaseous circumstellar disk could explain the contin…

Dynamical evolution and end states of active and inactive Centaurs

Julio A. Fernández, Michel Helal, Tabaré Gallardo

We numerically study the dynamical evolution of observed samples of active and inactive Centaurs and clones that reach the Jupiter-Saturn region. Our aim is to compare the evolutio…

Resonances in the asteroid and trans-Neptunian belts: a brief review

Tabare Gallardo

Mean motion resonances play a fundamental role in the dynamics of the small bodies of the Solar System. The last decades of the 20th century gave us a detailed description of the d…

The end states of long-period comets and the origin of Halley-type comets

Julio A. Fernández, Tabaré Gallardo, Juan D. Young

We analyze a sample of 73 old long-period comets (LPCs) (orbital periods yr) with perihelion distances au, discovered in the period 1850-2014. We cloned…

Planetary and satellite three body mean motion resonances

Tabaré Gallardo, Leonardo Coito, Luciana Badano

We propose a semianalytical method to compute the strengths on each of the three massive bodies participating in a three body mean motion resonance (3BR). Applying this method we e…

Assessing the physical nature of near-Earth asteroids through their dynamical histories

Julio A. Fernández, Andrea Sosa, Tabaré Gallardo +1

We analyze a sample of 139 near-Earth asteroids (NEAs), defined as those that reach perihelion distances au, and that also fulfill the conditions of approaching or crossi…

Atlas of three body mean motion resonances in the Solar System

Tabaré Gallardo

We present a numerical method to estimate the strengths of arbitrary three body mean motion resonances between two planets in circular coplanar orbits and a massless particle in an…

Survey of Kozai Dynamics Beyond Neptune

Tabare Gallardo, Gaston Hugo, Pablo Pais

We study the Kozai dynamics affecting the orbital evolution of transneptunian objects being captured or not in MMR with Neptune. We provide energy level maps of the type (ω,q) desc…

Origin and Sustainability of The Population of Asteroids Captured in the Exterior Resonance 1:2 with Mars

T. Gallardo, J. Venturini, F. Roig +1

At present, approximately 1500 asteroids are known to evolve inside or sticked to the exterior 1:2 resonance with Mars at a = 2.418 AU, being (142) Polana the largest member of thi…

The Relativistic Factor in the Orbital Dynamics of Point Masses

Federico Benitez, Tabare Gallardo

There is a growing population of relativistically relevant minor bodies in the Solar System and a growing population of massive extrasolar planets with orbits very close to the cen…
