  • Spiral instability can drive thermonuclear explosions in binary white dwarf mergers 

    kashyap, Rahul; Fisher, Robert T.; García-Berro Montilla, Enrique; Aznar Siguan, Gabriela; Ji, Suoqing; Loren Aguilar, Pablo (2015-02-10)
    Article
    Open Access
    Thermonuclear, or Type Ia supernovae (SNe Ia), originate from the explosion of carbon-oxygen white dwarfs, and serve as standardizable cosmological candles. However, despite their importance, the nature of the progenitor ...
  • Estrategias e indicadores para la evaluación de la docencia en el marco del EEES 

    García-Berro Montilla, Enrique; Dapia de Dios, Francesc; Amblas Marondo, Gemma; Bugeda Castelltort, Gabriel; Roca Martín, Santiago (2009)
    Article
    Open Access
    En este artículo se describen las estrategias que ha emprendido la Universidad Politécnica de Cataluña (UPC) para implantar las nuevas titulaciones de Ingeniería adaptadas al Espacio Europeo de Enseñanza Superior (EEES). ...
  • The variation of the fine structure constant: testing the dipole model with thermonuclear supernovae 

    Kraiselburd, L; Landau, S. J.; García-Berro Montilla, Enrique; Negrelli, C (2015-05-01)
    Article
    Restricted access - publisher's policy
    The large-number hypothesis conjectures that fundamental constants may vary. Accordingly, the space-time variation of fundamental constants has been an active subject of research for decades. Recently, using data obtained ...
  • Constraining the neutrino magnetic dipole moment from white dwarf pulsations 

    Corsico, Alejandro H.; Althaus, Leandro G.; Miller Bartolami, Marcelo M.; Kepler, S.O.; García-Berro Montilla, Enrique (2014-08-01)
    Article
    Open Access
    Pulsating white dwarf stars can be used as astrophysical laboratories to constrain the properties of weakly interacting particles. Comparing the cooling rates of these stars with the expected values from theoretical models ...
  • The white dwarf cooling sequence of 47 Tucanae 

    García-Berro Montilla, Enrique; Torres Gil, Santiago; Althaus, Leandro G.; Miller Bartolami, Marcelo M. (2014-11)
    Article
    Open Access
    Context. 47 Tucanae is one of the most interesting, well-observed, and theoretically studied globular clusters. This allows us to determine the reliability of our understanding of white dwarf cooling sequences, to compare ...
  • Constraining the double-degenerate scenario for Type Ia supernovae from merger ejected matter 

    Levanon, Naveh; Soker, Noam; García-Berro Montilla, Enrique (2015-03-01)
    Article
    Open Access
    We follow the mass expelled during the WD-WD merger process in a particular case of the double-degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting ...
  • White dwarf evolutionary sequences for low-metallicity progenitors: The impact of third dredge-up 

    Althaus, Leandro G.; Camisassa, Maria E; Miller Bertolami, Marcelo M; Corsico, Alejandro H.; García-Berro Montilla, Enrique (2015-04-01)
    Article
    Open Access
    Context. White dwarfs are nowadays routinely used as reliable cosmochronometers, allowing several stellar populations to be dated.; Aims. We present new white dwarf evolutionary sequences for low-metallicity progenitors. ...

  • An efficient multi-step iterative method for computing the numerical solution of systems of nonlinear equations associated with ODEs 

    Ullah, Malik Zaka; Serra Capizzano, Stefano; Ahmad, Fayyaz (2015-01)
    Article
    Restricted access - publisher's policy
    We developed multi-step iterative method for computing the numerical solution of nonlinear systems, associated with ordinary differential equations (ODEs) of the form L(x(t)) + f(x(t)) = g(t) : here L(.) is a linear ...
  • Underground study of the 17O(p,alpha)18F reaction relevant for explosive hydrogen burning 

    Di Leva, A; Scott, D.A.; Caciolli, A.; Formicola, A.; Strieder, F.; Aliotta, M.; Anders, M.; Bemmerer, D.; Broggini, C.; Corvisiero, P.; Elekes, Z.; Fulop, Zs.; Gervino, G.; Guglielmetti, G.; Gustavino, C.; Gyurky, Gy.; Imbriani, G.; José Pont, Jordi; Junker, M.; et al., . (2014-01)
    Article
    Open Access
    The 17O(p,γ )18F reaction affects the production of key isotopes (e.g., 18F and 18O) in the explosive hydrogen burning that powers classical novae. Under these explosive conditions, the reaction rate is dominated by ...
