    • Four-body co-circular central configurations 

      Cors Iglesias, Josep Maria; Roberts, Gareth E. (2012-02)
      Article
      Accés obert
      We classify the set of central configurations lying on a common circle in the Newtonian four-body problem. Using mutual distances as coordinates, we show that the set of four-body co-circular central configurations with ...

      Article
      Accés obert
      We 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. ...

      Article
      Accés obert
      Hip–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. ...

      Article
      Accés obert
      The 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 ...

    • Numerical exploration of the limit ring problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Hall, G.R. (2013-04)
      Article
      Accés obert
      The 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 kn-body problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria (2019-08-15)
      Article
      Accés obert
      We consider planar central configurations of the Newtonian kn-body problem consisting in k groups of regular n-gons of equal masses, called (k, n)-crown. We derive the equations of central configurations for a general (k, ...

      Cors Iglesias, Josep Maria; Palacián Subiela, Jesús Francisco; Yanguas Sayas, Patricia (2019-01-01)
      Article
      Accés obert
      Within the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM $4$-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ...

      We consider planar central configurations of the Newtonian 2n-body problem consisting in two twisted regular n-gons of equal masses. We prove the conjecture that for n=5 all convex central configurations of two twisted ...
