    We have performed deep X-ray observations of the remnant of Kepler's supernova (SN 1604) as a Key Project of the Suzaku Observatory. Our main goal is to detect secondary Fe-peak elements in the supernova (SN) ejecta to ...
  • Is there a hidden hole in type la supernova remnants?

    In this paper, we report on the bulk features of the hole carved by the companion star in the material ejected during a Type Ia supernova (SN Ia) explosion. In particular we are interested in the long-term evolution of the ...
  • The origin of the iron-rich knot in Tycho's supernova remnant

    X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosions. Here we present detailed imaging and ...
  • The post-merger magnetized evolution of white dwarf binaries: The double-degenerate channel of sub-Chandrasekhar type Ia supernovae and the formation of magnetized white dwarfs 

    Ji, Suoqing; Fisher, Robert T.; García-Berro Montilla, Enrique; Tzeferacos, Petros; Jordan, George C.; Lee, Dongwook; Lorén Aguilar, Pablo; Cremer, Pascal; Behrends, Jan (2013-08-20)

    Type Ia supernovae (SNe Ia) play a crucial role as standardizable cosmological candles, though the nature of their progenitors is a subject of active investigation. Recent observational and theoretical work has pointed to ...
  • 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
    Accés obert
    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 ...
