    Article
    Accés obert
    The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possible to use its slope to test the existence ...

    Article
    Accés obert
    High-field magnetic white dwarfs have been long suspected to be the result of stellar mergers. However, the nature of the coalescing stars and the precise mech anism that produces the magnetic field are still unknown. ...

    García-Berro Montilla, Enrique; Torres Gil, Santiago; Camacho Díaz, Judit; Soker, Noam; Kashi, Amit (2013-05)
    Article
    Accés obert
    We argue that the multiple shells of circumstellar material (CSM) and the supernovae (SNe) ejecta interaction with the CSM starting 59 d after the explosion of the Type Ia SN PTF 11kx are best described by a violent prompt ...

    Article
    Accés obert
    El concepte de sostenibilitat requereix del concepte de societat sostenible. Quan ens referim a la sostenibilitat d'un sistema, ens referim a la d'un sistema humà, amb els seus aspectes materials i culturals, i que ha ...
  • High-proper-motion white dwarfs and halo dark matter 

    Torres Gil, Santiago; García-Berro Montilla, Enrique; Burkert, Andreas; Isern Vilaboy, Jordi (Blackwell, 2002-11)
    Article
    Accés obert
    The interpretation of the old, cool white dwarfs recently found by Oppenheimer et al. is still controversial. Whereas these authors claim that they have finally found the elusive ancienthalo white dwarf population that ...
  • Monte Carlo simulations of post-common-envelope white dwarf + main sequence binaries: The effects of including recombination energy 

    Zorotovic, Monica; García-Berro Montilla, Enrique; Schreiber, Mathias R.; Camacho Díaz, Judit; Torres Gil, Santiago; Rebassa Mansergas, Alberto; Gänsicke, Boris T. (2014-08-20)
    Article
    Accés obert
    Context. Detached white dwarf + main sequence (WD+MS) post-common-envelope binaries (PCEBs) are perhaps the most suitable objects for testing predictions of close-compact binary-star evolution theories, in particular, ...
