Ejection-collision orbits in the symmetric collinear four–body problem
Álvarez Ramírez, Martha; Barrabés Vera, Esther; Medina, M.; Ollé Torner, Mercè (2019-06-15)
Article
Accés obertIn this paper, we consider the collinear symmetric four-body problem, where four masses and a¿>¿0, are aligned in this order and move symmetrically about their center of mass. We introduce regularized variables to deal ... -
Ejection–collision orbits in two degrees of freedom problems in celestial mechanics

Article
Accés obertIn a general setting of a Hamiltonian system with two degrees of freedom and assuming some properties for the undergoing potential, we study the dynamics close and tending to a singularity of the system which in models of ... -
Fast numerical computation of Lissajous and quasi-halo libration point trajectories

Text en actes de congrés
Accés obertIn this paper we present a methodology for the automatic generation of quasi–periodic libration point trajectories (Lissajous and quasi–halo) of the Spatial, Circular Restricted Three–Body Problem. This methodology is ... -
HAmsys 2014
Ollé Torner, Mercè; Barrabés Vera, Esther; Gómez Muntané, Gerard; Mondelo González, José María (2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn this talk we give an explanation of transport in the solar system based in dynamical systems theory. More concretely we consider (as a first approximation) different bicircular problems (i.e. Sun, Jupiter, a planet ... -
Highly eccentric hip-hop solutions of the 2N-body problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2010-02)
Article
Accés obertWe show the existence of families of hip-hop solutions in the equal-mass 2N-body problem which are close to highly eccentric planar elliptic homographic motions of 2N bodies plus small perpendicular non-harmonic oscillations. ... -

Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2006-09)
Article
Accés obertHip–Hop solutions of the 2N–body problem with equal masses are shown to exist using an analytic continuation argument. These solutions are close to planar regular 2N–gon relative equilibria with small vertical oscillations. ... -

Invariant manifolds of L_3 and horseshoe motion in the restricted three-body problem
Barrabés Vera, Esther; Ollé Torner, Mercè (2005)
Article
Accés obertIn this paper, we consider horseshoe motion in the planar restricted three-body problem. On one hand, we deal with the families of horseshoe periodic orbits (which surround three equilibrium points called L3, L4 and L5), ... -
J2 effect and elliptic inclined periodic orbits in the collision three-body problem

Article
Accés obertThe existence of a new class of inclined periodic orbits of the collision restricted three{body problem is shown. The symmetric periodic solutions found are perturbations of elliptic kepler orbits and they exist only for ... -
