  • A population synthesis study of the MS+WD population in the SDSS 

    García-Berro Montilla, Enrique; Torres Gil, Santiago; Camacho Díaz, Judit; Rebassa Mansergas, Alberto; Gänsicke, Boris T.; Schreiber, Mathias R.; Zorotovic, Mónica (Astronomical Society of the Pacific Conference Series (ASP), 2015-06-01)
    Article
    Accés obert
    Detached white dwarf + main sequence (WD+MS) systems represent the simplest population of post-common envelope binaries (PCEBs), and their ensemble properties carry important information about common-envelope phase. However, ...

  • Type Ia supernovae: Can Coriolis force break the symmetry of the gravitational confined detonation explosion mechanism? 

    García Senz, Domingo; Cabezón, Rubén Martin; Domínguez, Inmaculada; Thielemann, Friedrich-K (Institute of Physics (IOP), 2016-03-10)
    Article
    Accés obert
    © 2016. The American Astronomical Society. All rights reserved.. Currently the number of models aimed at explaining the phenomena of type Ia supernovae is high and distinguishing between them is a must. In this work we ...
  • Detached cataclysmic variables are crossing the orbital period gap 

    Zorotovic, Mónica; Schreiber, Mathias R.; Parsons, S. G.; Gaensicke, B. T.; Hardy, A.; Agurto Gangas, C.; Nebot Gómez-Moran, Ada; Rebassa Mansergas, Alberto; Schowpe, A. D. (2016-04-21)
    Article
    Accés obert
    A central hypothesis in the theory of cataclysmic variable (CV) evolution is the need to explain the observed lack of accreting systems in the similar or equal to 2-3 h orbital period range, known as the period gap. The ...
  • El impacto de las políticas de evaluación del profesorado en la posición en los ránquines universitarios: el caso de la Universidad Politécnica de Cataluña 

    García-Berro Montilla, Enrique; Roca Martín, Santiago; Navallas Ramos, Francisco Javier; Soriano Ibáñez, Miguel; Ras Sabido, Antoni (2016-01)
    Article
    Accés obert
    La universidad española ha afrontado con éxito el tránsito entre una universidad clásica, eminentemente docente, y una universidad moderna, en la que la investigación juega un papel esencial. Gran parte de este éxito reside ...
  • The white dwarf population of NGC 6397 

    Torres Gil, Santiago; García-Berro Montilla, Enrique; Althaus, Leandro G.; Camisassa, Maria E (2015-09-01)
    Article
    Accés obert
    Context. NGC 6397 is one of the most interesting, well-observed, and most thoroughly theoretically studied globular clusters. The existing wealth of observations allows us to study the reliability of the theoretical white ...
  • Is the central binary system of the planetary nebula Henize 2-428 a type Ia supernova progenitor? 

    García-Berro Montilla, Enrique; Soker, Noam; Althaus, Leandro G.; Ribas Canudas, Ignasi; Morales Peralta, Juan Carlos (2016-05-01)
    Article
    Accés restringit per política de l'editorial
    We critically discuss the recent observations of the binary system at the center of the bipolar planetary nebula Henize 2-428. We find that the proposed explanation of two equal-mass degenerate objects with a total mass ...
  • Spectroscopy of Ne 19 for the thermonuclear O 15 (alfa,gamma) Ne 19 and F 18 (pi,alfa) O 15 reaction rates 

    Parikh, Anuj Ramesh; Laird, A.M.; de Séréville, N (2015-11-20)
    Article
    Accés obert
    Uncertainties in the thermonuclear rates of the O15(a,¿)19Ne and 18F(p,a)15O reactions affect model predictions of light curves from type I x-ray bursts and the amount of the observable radioisotope F18 produced in classical ...
  • Image data compression with hierarchical pixel averaging and fully adaptive prediction error coder 

    Iudica, Riccardo; Artigues, Gabriel; Portell, Jordi; García-Berro Montilla, Enrique (2015-06-04)
    Article
    Accés obert
    The fully adaptive prediction error coder (FAPEC) is an entropy coder that typically offers better results than the adaptive Rice compressor. It uses basic preprocessing stages such as delta preprocessing, but it can also ...
  • Discovery of Cl-34g,Cl-m(p,gamma)Ar-35 resonances activated at classical nova temperatures 

    Fry, C.; Wrede, Christopher; Bishop, Shawn M.; Brown, B. A.; Chen, Alan A.; Faestermann, Thomas; Hertenberger, R.; Parikh, Anuj Ramesh; Perez Loureiro, D; Wirth, Hans Friedrich; Garcia, A.; Ortez, Ronaldo (2015-01-13)
    Article
    Accés obert
    Background: The thermonuclear Cl-34g,Cl-m(p,gamma)Ar-35 reaction rates are unknown due to a lack of experimental nuclear physics data. Uncertainties in these rates translate to uncertainties in S-34 production in models ...
