  • Axisymmetric smoothed particle hydrodynamics with self-gravity 

    García Senz, Domingo; Relano, A; Cabezón Gómez, Rubén Martín; Bravo Guil, Eduardo (2009-01)
    Article
    Open Access
    The axisymmetric form of the hydrodynamic equations within the smoothed particle hydrodynamics (SPH) formalism is presented and checked using idealized scenarios taken from astrophysics (free fall collapse, implosion and ...
  • Constraining deflagration models of type Ia supernovae through intermediate-mass elements 

    García Senz, Domingo; Bravo Guil, Eduardo; Cabezón Gómez, Rubén Martín; Woosley, S E (2007-05)
    Article
    Restricted access - publisher's policy
    The physical structure of a nuclear flame is a basic ingredient of the theory of Type Ia supernovae (SNe Ia). Assuming an exponential density reduction with several characteristic times, we have followed the evolution of ...
  • High-temperature combustion: Approaching equilibrium using nuclear networks 

    Cabezón Gómez, Rubén Martín; García Senz, Domingo; Bravo Guil, Eduardo (2004-04)

  • Improving smoothed particle hydrodynamics with an integral approach to calculating gradients 

    García Senz, Domingo; Cabezón Gómez, Rubén Martín; Escartín Vigo, José Antonio (2012-01-26)
    Article
    Open Access
    Context. The smoothed particle hydrodynamics (SPH) technique is a well-known numerical method that has been applied to simulate the evolution of a wide variety of systems. Modern astrophysical applications of the method ...
  • Pulsating reverse detonation models of Type Ia supernovae. II. Explosion 

    Bravo Guil, Eduardo; García Senz, Domingo; Cabezón Gómez, Rubén Martín; Domínguez, Inmaculada (2009-04)
    Article
    Restricted access - publisher's policy
    Observational evidences point to a common explosion mechanism of Type Ia supernovae based on a delayed detonation of a white dwarf (WD). However, all attempts to find a convincing ignition mechanism based on a delayed ...
  • Smoothed particle hydrodynamics: checking a tensor approach to calculating gradients 

    Escartín Vigo, José Antonio; García Senz, Domingo; Cabezón Gómez, Rubén Martín (2013)
    Conference lecture
    Open Access
  • Surface and core detonations in rotating white dwarfs 

    García Senz, Domingo; Cabezón Gómez, Rubén Martín; Domínguez, I. (Institute of Physics (IOP), 2018-07-20)
    Article
    Open Access
    The feasibility of the double detonation mechanism—surface helium detonation followed by complete carbon detonation of the core—in a rotating white dwarf with mass ;1Me is studied using three-dimensional hydrodynamic ...
  • Testing the concept of integral approach to derivatives within the smoothed particle hydrodynamics technique in astrophysical scenarios 

    Cabezón Gómez, Rubén Martín; García Senz, Domingo; Escartín Vigo, José Antonio (2012)
    Article
    Open Access
    Context. The smoothed particle hydrodynamics (SPH) technique is a well-known numerical method that has been applied to simulating the evolution of a wide variety of systems. Modern astrophysical applications of the method ...
  • The elusive nature of the r-stars 

    Domínguez, Inmaculada; Piersanti, Luciano; Cabezón Gómez, Rubén Martín; Zamora, O.; García Senz, Domingo; Abia, C.; Straniero, Oscar (2010-10-10)
    Article
    Open Access
    R stars are carbon stars, less luminous and hotter than the carbon stars evolving along the AGB phase. Thus, their carbon enrichment cannot be a consequence of the third dredge-up, a fact also in agreement with the lack ...
