  • Precessing models and eventual links with galaxy warps 

    Barajas Pichardo, Daniel (Universitat Politècnica de Catalunya, 2010-11)
    Master thesis
    Open Access
    The Restricted Three Body problem is a basic model in celestial mechanics and it has been extensively used in the design of some spatial missions. Sometimes, the designers of these missions consider other similar models ...
  • Rings and spirals in barred galaxies III. Further comparisons and links to observations 

    Masdemont Soler, Josep; Bosma, A.; Romero Gómez, Mercè; Athanassoula, Evangelie (2010)
    Restricted access - publisher's policy
    In a series of papers, we propose a theory to explain the formation and properties of rings and spirals in barred galaxies. The building blocks of these structures are orbits guided by the manifolds emanating from the ...
  • The contribution of oxygen-neon white dwarfs to the MACHO content of the Galactic halo 

    Camacho Díaz, Judit; Torres Gil, Santiago; Isern Vilaboy, Jordi; Althaus, Leandro Gabriel; García-Berro Montilla, Enrique (2007-06-13)
    Open Access
    Context. The interpretation of microlensing results towards the Large Magellanic Cloud (LMC) still remains controversial. White dwarfs have been proposed to explain these results and, hence, to contribute significantly ...
  • Three kinematical methods to identify local galactic structures 

    Cubarsí Morera, Rafael; Alcobé López, Santiago; Vidojevic, S.; Ninkovic, S. (2010-05)
    Conference lecture
    Open Access
    Method one: by combining a sampling parameter related to an isolating integral of the stellar motion, an optimisation of the mixture approach, and a maximisation of the partition entropy for the constituent populations ...
  • Un planeta con dos soles. ¿Tatooine o Kepler-16b? 

    Moreno Lupiáñez, Manuel (2011-10-25)
    External research report
    Open Access
    La existencia de un mundo con atardeceres dobles, similar al que se mostró en la película "Star Wars" hace más de 30 años, ya es un hecho científico. La misión Kepler, de la Nasa, ha logrado la primera detección directa ...
