    • Analytical and numerical results on families of n-ejection-collision orbits in the RTBP 

      Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2020-11-01)
      Article
      Restricted access - publisher's policy
      In the planar RTBP with mass ratio µ we regularise the singularity at one of the primaries by means of Levi-Civita’s transformation in a rotating frame. We solve the variational equations in a neighbourhood of the ...

    • Ejection-collision orbits in the Restricted three-body problem 

      Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2018-02)
      Article
      Open Access
      In this paper we analyse the ejection-collision (EC) orbits of the planar restricted three body problem. Being µ¿¿¿(0, 0.5] the mass parameter, and taking the big (small) primary with mass (µ), an EC orbit will be an orbit ...
    • 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
      Open Access
      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. ...
    • Hip-hop solutions of the 2N-body problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2006-09)
      Article
      Open Access
      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. ...
    • J2 effect and elliptic inclined periodic orbits in the collision three-body problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2008-01)
      Article
      Open Access
      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 ...
    • Llums i ombres de la física: el projecte Manhattan 

      Soler Villanueva, Jaume (2009-11-24)
      Audiovisual
      Open Access
      En aquesta xerrada es fa un repàs ràpid de l'evolució de la Física Nuclear fins a finals dels anys 30 i després es veuen les raons científiques, polítiques i militars que van portar al Projecte Manhattan: la fabricació ...

    • Regularisation in ejection-collision orbits of the RTBP 

      Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2018)
      Conference report
      Open Access
      Numerical explorations confirm well-known analytical results on the ex-istence of ejection-collision orbits in the restricted three-body problem for veryrestrictive values of the Jacobi constantC. For different values ...
