      The Gaia mission has provided an unprecedented wealth of information about the white dwarf population of our Galaxy. In particular, our studies show that the sample up to 100\,pc from the Sun can be considered as practically ...

    • Effects of Ne-22 sedimentation and metallicity on the local 40 pc white dwarf luminosity function 

      Tononi García, Jordi; Torres Gil, Santiago; García-Berro Montilla, Enrique; Camisassa, María E.; Althaus, Leandro G.; Rebassa Mansergas, Alberto (EDP Sciences, 2019-08-06)

      We analyzed the effect of the sedimentation of 22Ne on the local white dwarf luminosity function by studying scenarios under different Galactic metallicity models. Methods. We use an advanced population synthesis code based ...

    • 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 ...
