Article
Open AccessIn 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 ... 
Ejection–collision orbits in two degrees of freedom problems in celestial mechanics
Alvarez Ramírez, Martha; Barrabés Vera, Esther; Medina, M.; Ollé Torner, Mercè (Springer Nature, 20210801)
Article
Open AccessIn 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 quasihalo libration point trajectories
Mondelo, Josep Maria; Barrabés Vera, Esther; Gómez Muntané, Gerard; Ollé Torner, Mercè (2012)
Conference report
Open AccessIn 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 ...

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
