  • A note on the dynamics around the L1,2 Lagrange points of the Earth-Moon system in a complete solar system model 

    Tang, Guojian; Gomez Muntaner, Gerard; Masdemont Soler, Josep; Yijun, L. (2012)
    Text en actes de congrés
    Accés obert
    The purpose of this paper is the study of the phase space around the collinear libration points L1 and L2 of the Earth–Moon system when the gravitational effects of the remaining bodies of the Solar System are taken into ...
  • A note on the dynamics around the Lagrange collinear points of the Earth-Moon system in a complete Solar System model 

    Lian, Yijun; Gómez Muntané, Gerard; Masdemont Soler, Josep; Tang, Guojian (2013-02)
    Article
    Accés restringit per política de l'editorial
    In this paper we study the dynamics of a massless particle around the L 1,2 libration points of the Earth–Moon system in a full Solar System gravitational model. The study is based on the analysis of the quasi-periodic ...
  • Combined low-thrust propulsion and invariant manifold trajectories to capture NEOs in the Sun-Earth circular restricted three-body problem 

    Mingotti, Giorgio; Sánchez Cuartielles, Joan Pau; McInnes, Colin (2014-11-01)
    Article
    Accés restringit per política de l'editorial
    In this paper, a method to capture near-Earth objects (NEOs) incorporating low-thrust propulsion into the invariant manifolds technique is investigated. Assuming that a tugboat-spacecraft is in a rendez-vous condition with ...
  • Detecting invariant manifolds using hyperbolic Lagrangian coherent structures 

    Pérez, Daniel; Gómez Muntané, Gerard; Masdemont Soler, Josep (2012)
    Article
    Accés obert
    Using as reference test model the Planar Circular Restricted Three Body Prob- lem, this paper explores its Lagrangian Coherent Structures, as well as its Hy- perbolic Lagrangian Coherent Structures. The purpose is to ...

    Accés obert
    Using as reference test model the Planar Circular Restricted Three Body Problem, this paper explores its Lagrangian Coherent Structures, as well as its Hyperbolic Lagrangian Coherent Structures. The purpose is to identify ...
  • Fast numerical computation of Lissajous and quasi-halo libration point trajectories 

    Mondelo, Josep Maria; Barrabes, E.; Gómez Muntané, Gerard; Ollé Torner, Mercè (2012)
    Text en actes de congrés
    Accés obert
    In 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 ...
  • Further advances on low-energy lunar impact dynamics 

    Alessi, Elisa Maria; Gómez, Gerard; Masdemont Soler, Josep (2010-02)
    Article
    Accés restringit per política de l'editorial
    We extend the analysis, started in a previous work [1], concerning the formation of lunar impact craters due to low-energy trajectories. First, we adopt the Circular Restricted Three- Body Problem and consider different ...
  • Methodology and estimation costs for proximity maneuvering spacecraft formations in the vicinity of libration points 

    Garcia Taberner, Laura; Masdemont Soler, Josep (2012)
    Text en actes de congrés
    Accés obert
    The aim of this paper is to study and provide estimations of the cost of reconfiguration maneuvers in the neighbor- hood of L1 and L2 libration points of the Sun-Earth system. The problem is considered as a function of ...
  • On the mechanisms of natural transport in the solar system 

    Masdemont Soler, Josep; Ren, Yuan; Gómez Muntané, Gerard; Fantino, Elena (2010)
    Text en actes de congrés
    Accés obert
    Some minor bodies in the solar system (i.e., comets, asteroids and planetary ejecta) are capable of performing transfers from their original location to very distant places, provided they possess sufficiently large ...
  • The scattering map in the spatial Hill's problem 

    Delshams Valdés, Amadeu; Masdemont Soler, Josep; Roldán González, Pablo (2006-11)
    Article
    Accés obert
    We present a framework and methodology to compute the scattering map associated to heteroclinic trajectories in the spatial Hill's problem. The scattering map can be applied to design of zero-cost transfer trajectories in ...
  • Tools to detect structures in dynamical systems using Jet Transport 

    Pérez-Palau, Daniel; Masdemont Soler, Josep; Gómez Muntané, Gerard (2015-11-01)
    Article
    Accés obert
    This paper is devoted to the development of some dynamical indicators that allow the determination of regions and structures that separate different dynamic regimes in autonomous and non-autonomous dynamical systems. The ...
  • Two mechanisms of natural transport in the Solar System 

    Ren, Yuan; Gomez Muntaner, Gerard; Masdemont Soler, Josep; Fantino, Elena (2011)
    Article
    Accés restringit per política de l'editorial
    In this paper, two natural transport mechanisms in Solar System are considered. The first is a short-time transport, and is based on the existence of ‘‘pseudo-heteroclinic’’ connections between libration point orbits of ...
