Dynamical aspects of multiround horseshoeshaped homoclinic orbits in the RTBP
Ollé Torner, Mercè; Barrabés Vera, Esther (200911)
Article
Restricted access  publisher's policyWe consider the planar restricted threebody problem and the collinear equilibrium point L3, as an example of a center×saddle equilibrium point in a Hamiltonian with two degrees of freedom.We explore numerically the ... 
Dynamics of the parabolic restricted threebody problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Ollé Torner, Mercè (20151201)
Article
Open AccessThe main purpose of the paper is the study of the motion of a massless body attracted, under the Newton's law of gravitation, by two equal masses moving in parabolic orbits all over in the same plane, the planar parabolic ... 
Ejectioncollision orbits in the symmetric collinear four–body problem
Alvarez Ramírez, Martha; Barrabés Vera, Esther; Medina, M.; Ollé Torner, Mercè (20190615)
Article
Restricted access  publisher's policyIn this paper, we consider the collinear symmetric fourbody 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 ... 
HAmsys 2014
Ollé Torner, Mercè; Barrabés Vera, Esther; Gomez Muntane, Gerard; Mondelo, Josep Maria (2014)
Conference report
Restricted access  publisher's policyIn 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 hiphop solutions of the 2Nbody problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol, Conxita; Soler Villanueva, Jaume (201002)
Article
Open AccessWe show the existence of families of hiphop solutions in the equalmass 2Nbody problem which are close to highly eccentric planar elliptic homographic motions of 2N bodies plus small perpendicular nonharmonic oscillations. ...

Invariant manifolds of L_3 and horseshoe motion in the restricted threebody problem
Barrabés Vera, Esther; Ollé Torner, Mercè (2005)
Article
Open AccessIn this paper, we consider horseshoe motion in the planar restricted threebody problem. On one hand, we deal with the families of horseshoe periodic orbits (which surround three equilibrium points called L3, L4 and L5), ... 
Low‐cost trajectories using dynamical systems

Numerical continuation of families of homoclinic connections of periodic orbits in the RTBP
Ollé Torner, Mercè; Barrabés Vera, Esther; Mondelo González, José María (200912)
Article
Restricted access  publisher's policyThe goal of this paper is the numerical computation and continuation of homoclinic connections of the Lyapunov families of periodic orbits (p.o.) associated with the collinear equilibrium points, L1, L2 and L3, of ... 
Numerical exploration of the limit ring problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Hall, G.R. (201304)
Article
Open AccessThe aim of this work is to provide an insight of an idealized model of a planetary ring. The model is a limit case of the planar circular restricted 1 + n body problem, where an infinitesimal particle moves under the ... 
On central configurations of the knbody problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria (20190815)
Article
Restricted access  publisher's policyWe consider planar central configurations of the Newtonian knbody problem consisting in k groups of regular ngons of equal masses, called (k, n)crown. We derive the equations of central configurations for a general (k, ... 
On strictly convex central configurations of the 2nbody problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria (20180101)
Article
Restricted access  publisher's policyWe consider planar central configurations of the Newtonian 2nbody problem consisting in two twisted regular ngons of equal masses. We prove the conjecture that for n=5 all convex central configurations of two twisted ... 
Pseudoheteroclinic connections between bicircular restricted fourbody problems
Barrabés Vera, Esther; Gomez Muntané, Gerard; Mondelo, Josep Maria; Ollé Torner, Mercè (20161011)
Article
Open AccessIn this paper, we show a mechanism to explain transport from the outer to the inner Solar system. Such a mechanism is based on dynamical systems theory. More concretely, we consider a sequence of uncoupled bicircular ... 
Spatial collinear restricted fourbody problem with repulsive Manev potential
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Vidal Díaz, Claudio (20170901)
Article
Open AccessWe outline some aspects of the dynamics of an infinitesimal mass under the Newtonian attraction of three point masses in a symmetric collinear relative equilibria configuration when a repulsive Manev potential (1/r+e/r2 ... 
Tails and bridges in the parabolic restricted threebody problem
Barrabés Vera, Esther; Cors Iglesias, Josep Maria; García Taberner, Laura; Ollé Torner, Mercè (20170101)
Article
Open AccessAfter a close encounter of two galaxies, bridges and tails can be seen between or around them. A bridge would be a spiral arm between a galaxy and its companion, whereas a tail would correspond to a long and curving set ...
