    • Constraining the double-degenerate scenario for Type Ia supernovae from merger ejected matter 

      Levanon, Naveh; Soker, Noam; García-Berro Montilla, Enrique (2015-03-01)
      Article
      Open Access
      We follow the mass expelled during the WD-WD merger process in a particular case of the double-degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting ...

    • Explaining the Type Ia supernova PTF 11kx with a violent prompt merger scenario 

      García-Berro Montilla, Enrique; Torres Gil, Santiago; Camacho Díaz, Judit; Soker, Noam; Kashi, Amit (2013-05)
      Article
      Open Access
      We argue that the multiple shells of circumstellar material (CSM) and the supernovae (SNe) ejecta interaction with the CSM starting 59 d after the explosion of the Type Ia SN PTF 11kx are best described by a violent prompt ...

    • 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
      Open Access
      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 ...

    • Oxygen-neon-rich merger during common envelope evolution 

      Canals, Pere; Torres Gil, Santiago; Soker, Noam (Oxford University Press, 2018-11-01)
      Article
      Open Access
      We conduct a population synthesis study of the common envelope evolution (CEE) of a white dwarf (WD) and an asymptotic giant branch (AGB) star and find that the potential number of type Ia supernovae (SNe Ia) from the core ...

    • Smoothed particle hydrodynamics simulations of the core-degenerate scenario for Type Ia supernovae 

      Aznar Siguan, Gabriela; García-Berro Montilla, Enrique; Lorén Aguilar, Pablo; Soker, Noam; Kashi, Amit (2015-07-01)
      Article
      Open Access
      The core-degenerate scenario for Type Ia supernovae involves the merger of the hot core of an asymptotic giant branch star and a white dwarf, and might contribute a non-negligible fraction of all thermonuclear supernovae. ...

    • The response of a helium white dwarf to an exploding Type Ia supernova 

      Papish, Oded; Soker, Noam; García-Berro Montilla, Enrique; Aznar Siguan, Gabriela (2015-05-01)
      Article
      Open Access
      We conduct numerical simulations of the interacting ejecta from an exploding CO white dwarf (WD) with a He WD donor in the double-detonation scenario for Type Ia supernovae (SNe Ia), and study the possibility of exploding ...
