    • Rotating type Ia SN progenitors: explosion and light curves 

      Domínguez, Inmaculada; Piersanti, L.; Bravo Guil, Eduardo; Tornambé, A.; Straniero, O.; Gagliardi, S. (2006-06)
      Article
      Accés restringit per política de l'editorial
      Based on the rigidly rotating progenitor models found to be able to grow up to the canonical Chandrasekhar mass limit and beyond, and undergo a thermonuclear explosion, we compute the explosions, detailed nucleosynthesis, ...

    • Supernovae and dark energy 

      Domínguez, Inmaculada; Bravo Guil, Eduardo; Piersanti, Luciano; Straniero, Oscar; Tornambé, Amedeo (Astronomical Society of the Pacific, 2008)
      Text en actes de congrés
      Accés obert
      A decade ago the observations of thermonuclear supernovae at high-redhifts showed that the expansion rate of the Universe is accelerating and since then, the evidence for cosmic acceleration has gotten stronger. This ...

    • 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
      Accés obert
      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 ...

    • The fate of CO white dwarfs that experience slow deflagrations 

      Bravo Guil, Eduardo; Domínguez, Inmaculada; Isern Vilaboy, Jordi (1999-10)
      Article
      Accés obert
      It has been suggested that the differences among the observational Type Ia supernovae (SNIa) set can be accounted for by invoking two regimes of propagation of combustion. Normal SNIa should be produced by rapid deflagrations ...

    • The impact of chemical differentiation of white dwarfs on thermonuclear supernovae 

      Bravo Guil, Eduardo; Althaus, Leandro Gabriel; García-Berro Montilla, Enrique; Domínguez, Inmaculada (2010-12-16)
      Article
      Accés obert
      Aims. Gravitational settling of 22Ne in cooling white dwarfs can affect the outcome of thermonuclear supernovae. We investigate how the supernova energetics and nucleosynthesis are in turn influenced by this process. We ...

    • Thermal X-ray emission from shocked ejecta in Type Ia supernova remnants: Prospects for explosion mechanism identification 

      Badenes Montoliu, Carles; Bravo Guil, Eduardo; Borkowski, K.J.; Domínguez, Inmaculada (2003-08)
      Article
      Accés restringit per política de l'editorial
      The explosion mechanism behind Type Ia supernovae is a matter of continuing debate. The diverse attempts to identify or at least constrain the physical processes involved in the explosion have been only partially successful ...

    • Type Ia supernovae and the 12C+12C reaction rate 

      Bravo Guil, Eduardo; Piersanti, Luciano; Domínguez, Inmaculada; Straniero, Oscar; Isern Vilaboy, Jordi; Escartín Vigo, José Antonio (2011-11-22)
      Article
      Accés obert
      Context. Even if the 12C+12C reaction plays a central role in the ignition of type Ia supernovae (SNIa), the experimental determination of its cross-section at astrophysically relevant energies (E ≲ 2 MeV) has never been ...

    • 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 ...
