5.9 keV Mn K-shell X-ray luminosity from the decay of 55Fe in Type Ia supernova models
I. R. Seitenzahl, A. Summa, F. Krauss +12
We show that the X-ray line flux of the Mn Kalpha line at 5.9 keV from the decay of 55Fe is a promising diagnostic to distinguish between Type Ia supernova (SN Ia) explosion models…
Testing the role of SNe Ia for Galactic chemical evolution of p-nuclei with 2D models and with s-process seeds at different metallicities
C. Travaglio, R. Gallino, T. Rauscher +2
The bulk of p isotopes is created in the 'gamma processes' mainly by sequences of photodisintegrations and beta decays in explosive conditions in Type Ia supernovae (SNIa) or in co…
OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation
C. Inserra, S. A. Sim, L. Wyrzykowski +31
We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred reds…
The white dwarf's carbon fraction as a secondary parameter of Type Ia supernovae
Sebastian T. Ohlmann, Markus Kromer, Michael Fink +4
Binary stellar evolution calculations predict that Chandrasekhar-mass carbon/oxygen white dwarfs (WDs) show a radially varying profile for the composition with a carbon depleted co…
New numerical solver for flows at various Mach numbers
F. Miczek, F. K. Roepke, P. V. F. Edelmann
Many problems in stellar astrophysics feature flows at low Mach numbers. Conventional compressible hydrodynamics schemes frequently used in the field have been developed for the tr…
SN2014J gamma-rays from the 56Ni decay chain
Roland Diehl, Thomas Siegert, Wolfgang Hillebrandt +7
The measurement of gamma-ray lines from the decay chain of 56Ni provides unique information about the explosion in supernovae. The 56Ni freshly-produced in the supernova powers the…
Radiogenic p-isotopes from SNIa, nuclear physics uncertainties and Galactic chemical evolution compared with values in primitive meteorites
C. Travaglio, R. Gallino, T. Rauscher +3
The nucleosynthesis of proton-rich isotopes is calculated for multi-dimensional Chandrasekhar-mass models of Type Ia supernovae with different metallicities. The predicted abundanc…
Early 56Ni decay γ-rays from SN2014J suggest an unusual explosion
Roland Diehl, Thomas Siegert, Wolfgang Hillebrandt +7
Type-Ia supernovae result from binary systems that include a carbon-oxygen white dwarf, and these thermonuclear explosions typically produce 0.5 M_solar of radioactive 56Ni. The 56…
Extensive HST Ultraviolet Spectra and Multi-wavelength Observations of SN 2014J in M82 Indicate Reddening and Circumstellar Scattering by Typical Dust
Ryan J. Foley, O. D. Fox, C. McCully +20
SN 2014J in M82 is the closest detected Type Ia supernova (SN Ia) in at least 28 years and perhaps in 410 years. Despite its small distance of 3.3 Mpc, SN 2014J is surprisingly fai…
