    • 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)
      Article
      Accés obert
      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 ...
    • The impact of chemical differentiation of white dwarfs on thermonuclear supernovae 

      Bravo Guil, Eduardo; Althaus, Leandro Gabriel; García-Berro Montilla, Enrique; Domínguez, Inmaculada (2010-12-16)
      Article
      Accés obert
      Aims. Gravitational settling of 22Ne in cooling white dwarfs can affect the outcome of thermonuclear supernovae. We investigate how the supernova energetics and nucleosynthesis are in turn influenced by this process. We ...
    • The white dwarf cooling sequence of NGC 6791: an unique tool for stellar astrophysics 

      García-Berro Montilla, Enrique; Torres Gil, Santiago; Renedo Rouco, Isabel; Camacho Díaz, Judit; Althaus, Leandro Gabriel; Córsico, Alejandro Hugo; Salaris, Maurizio; Isern Vilaboy, Jordi (2011)
      Article
      Accés obert
      Context. NGC 6791 is a well-studied, metal-rich open cluster that is so close to us that it can be imaged down to luminosities fainter than that of the termination of its white-dwarf cooling sequence, thus allowing for ...
    • White dwarf mergers and the origin of R coronae borealis stars 

      Lorén Aguilar, Pablo; Longland, Richard Leigh; José Pont, Jordi; García-Berro Montilla, Enrique; Althaus, Leandro Gabriel; Isern-Fontanet, J. (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We present a nucleosynthesis study of the merger of a 0.4 M⊙ helium white dwarf with a 0.8 M⊙ carbon-oxygen white dwarf, coupling the thermodynamic history of Smoothed Particle Hydrodynamics particles with a post-processing ...
