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…
Oxygen emission in remnants of thermonuclear supernovae as a probe for their progenitor system
D. Kosenko, W. Hillebrandt, M. Kromer +3
Recent progress in numerical simulations of thermonuclear supernova explosions brings up a unique opportunity in studying the progenitors of Type Ia supernovae. Coupling state-of-t…
Spitzer observations of SN 2014J and properties of mid-IR emission in Type Ia supernovae
J. Johansson, A. Goobar, M. M. Kasliwal +13
SN 2014J in M82 is the closest Type Ia supernova (SN Ia) in decades. The proximity allows for detailed studies of supernova physics and provides insights into the circumstellar and…
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…
