  • Latest generation white dwarf cooling models : theory and applications 

    Renedo Rouco, Isabel (Universitat Politècnica de Catalunya, 2014-11-13)
    Doctoral thesis
    Open Access
    White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, including globular and open clusters. ...
  • New chemical profiles for the asteroseismolofy of ZZ Ceti stars 

    Althaus, Leandro Gabriel; Córsico, Alejandro Hugo; Bischoff-Kim, A.; Romero, A.D.; Renedo Rouco, Isabel; García-Berro Montilla, Enrique; Miller Bertolami, Marcelo M (2010-07-10)
    Article
    Open Access
    We compute new chemical profiles for the core and envelope of white dwarfs appropriate for pulsational studies of ZZ Ceti stars. These profiles are extracted from the complete evolution of progenitor stars, evolved through ...
  • New cooling sequences for old white dwarfs 

    Renedo Rouco, Isabel; Althaus, Leandro Gabriel; Miller Bertolami, Marcelo M; Romero, A.D.; Córsico, Alejandro Hugo; Rohrmann, Rene Daniel; García-Berro Montilla, Enrique (2010-07)
    Article
    Restricted access - publisher's policy
    We present full evolutionary calculations appropriate for the study of hydrogen-rich DA white dwarfs. This is done by evolving white dwarf progenitors from the zero-age main sequence, through the core hydrogen-burning phase, ...
  • The effects of mixing on the evolution of intermediate-mass stars of different metallicities 

    Renedo Rouco, Isabel (Universitat Politècnica de Catalunya, 2009-02-04)
    Master thesis
    Open Access
    We study the evolution of solar (Z = 0.016) and metal-poor stars (Z = 0.001) of initial masses corresponding to 2M⊙, and 4M⊙, from the main sequence until the formation of degenerate carbon-oxygen cores. We explore the ...
  • 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
    Open Access
    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 ...
