    • 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)

      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 ...

    • One-armed spiral instability in double-degenerate post-merger accretion disks 

      kashyap, Rahul; Fisher, Robert T.; García-Berro Montilla, Enrique; Aznar-Siguán, Gabriela; Ji, Suoqing; Lorén Aguilar, Pablo (2017-05-01)
      Article
      Accés obert
      Increasing observational and theoretical evidence points to binary white dwarf (WD) mergers as the origin of some, if not most, normal Type Ia supernovae (SNe Ia). In this paper, we discuss the post-merger evolution of ...

    • Pseudo-heteroclinic connections between bicircular restricted four-body problems 

      Barrabés Vera, Esther; Gómez Muntané, Gerard; Mondelo González, José María; Ollé Torner, Mercè (2016-10-11)
      Article
      Accés obert
      In this paper, we show a mechanism to explain transport from the outer to the inner Solar system. Such a mechanism is based on dynamical systems theory. More concretely, we consider a sequence of uncoupled bicircular ...

    • 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
