    Isern Vilaboy, Jordi; Jean, Pierre; Bravo Guil, Eduardo; Knodlseder, Jurgen; Lebrun, François; Churazov, Eugene; Sunyaev, Rashid; Domingo, Alberto; Badenes, Carles; Hartmann, Dieter, H; Hoeflich, Peter; Renaud, Matthieu; Soldi, Simona; Elias Rosa, Nancy; Hernanz Carbó, Margarita; Domínguez Aguilera, Inmaculada; García Senz, Domingo; Lichti, G.G.; Vedrenne, G.; Von Ballmoos, Peter (EDP Sciences, 2016-04)
    Article
    Accés obert
    Context. The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the thermonuclear explosion of a C/O ...
  • Synthesis of C-rich dust in CO nova outbursts 

    José Pont, Jordi; Halabi, Ghina M.; El Eid, MounibF. (2016-09)
    Article
    Accés obert
    Context. Classical novae are thermonuclear explosions that take place in the envelopes of accreting white dwarfs in stellar binary systems. The material transferred onto the white dwarf piles up under degenerate conditions, ...
  • Reaction Rates of 64Ge(p,g)65As and 65As(p,g)66Se and the Extent of Nucleosynthesis in Type I X-Ray Bursts 

    Lam, Y.H.; He, J.J.; Parikh, Anuj Ramesh (2016-02)
    Article
    Accés obert
    The extent of nucleosynthesis in models of type I X-ray bursts (XRBs) and the associated impact on the energy released in these explosive events are sensitive to nuclear masses and reaction rates around the 64Ge waiting ...
  • The 20Ne(d,p)21Ne transfer reaction in relation to the s-process abundances 

    Nsangu, C.T.; Laird, A.M.; Parikh, Anuj Ramesh (Institute of Physics (IOP), 2016-01)
    Article
    Accés obert
    A study of the 20Ne(d,p)21Ne transfer reaction was performed using the Quadrupole Dipole Dipole Dipole (Q3D) magnetic spectrograph in Garching, Germany. The experiment probed excitation energies in 21Ne ranging from 6.9 ...
  • The transverse velocity shifts in protostellar jets: rotation or velocity asymmetries?

  • 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, ...
  • Stellar origins of extremely 13C- AND 15N-enriched presolar sic grains: Novae or Supernovae? 

    Liu, Nan; Nittler, L.; Alexander, Conel M. O'D.; Wang, Jianhua; Pignatari, Marco; José Pont, Jordi; Nguyen, Ann (2016-04-01)

    © 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 ...
