    • Early 56Ni decay gamma rays from SN2014J suggest an unusual explosion 

      Diehl, R.; Siegert, T.; Hillebrandt, W.; Grebenev, S.~A.; Greiner, J.; Krause, M.; Kromer, M.; Maeda, K.; Röpke, F.; Taubenberger, S. (2014-09-05)
      Type Ia supernovae result from binary systems that include a carbon-oxygen white dwarf, and these thermonuclear explosions typically produce 0.5 solar mass of radioactive 56Ni. The 56Ni is commonly believed to be buried ...

    • Radiogenic p-isotopes from type Ia supernova, nuclear physics uncertainties, and galactic chemical evolution compared with values in primitive meteorites 

      Travaglio, C.; Gallino, R.; Rauscher, T.; Dauphas, N.; Röpke, F. K.; Hillebrandt, W. (2014-11-10)
      The nucleosynthesis of proton-rich isotopes is calculated for multi-dimensional Chandrasekhar-mass models of Type Ia supernovae (SNe Ia) with different metallicities. The predicted abundances of the short-lived radioactive ...

    • SN2014J gamma rays from the $^56$Ni decay chain 

      Diehl, R.; Siegert, T.; Hillebrandt, W.; Krause, M.; Greiner, J.; Maeda, K.; Röpke, F.~K.; Sim, S.~A.; Wang, Wei; Zhang, X. (2015-02-01)
      Context. The detection and measurement of gamma-ray lines from the decay chain of 56Ni provides unique information about the explosion in supernovae. SN2014J at 3.3 Mpc is a sufficiently-nearby supernova of type Ia so that ...

    • Type Ia supernova progenitors, lifetime, and cosmic supernova rate 

      Kobayashi, C.; Nomoto, K. I. (Springer Nature, 2003)
      We make a comparison of the lifetime distribution derived from several models of Type Ia Supernovae (SNe Ia) and evaluate the SN Ia models from the observational constraints. Our SN Ia model, which is based on the single ...

    • Type Ia supernovae : Progenitors and diversities 

      Nomoto, K.; Uenishi, T.; Kobayashi, C.; Umeda, H.; Ohkubo, T.; Hachisu, I.; Kato, M. (Springer Nature, 2003)
      A key question for supernova cosmology is whether the peak luminosities of Type Ia supernovae (SNe Ia) are sufficiently free from the effects of cosmic and galactic evolution. To answer this question, we review the currently ...
