Title:	Early ⁵⁶Ni decay gamma rays from SN2014J suggest an unusual explosion.
Authors:	Diehl, Roland, Siegert, Thomas, Hillebrandt, Wolfgang, Grebenev, Sergei A., Greiner, Jochen, Krause, Martin, Kromer, Markus, Maeda, Keiichi, Röpke, Friedrich, Taubenberger, Stefan
Source:	Science (pre-March 2025). 9/5/2014, Vol. 345 Issue 6201, p1162-1165. 4p.
Subjects:	Supernovae, Thermonuclear reactions in stars, White dwarf stars, International Gamma-Ray Astrophysics Laboratory, Spectrum analysis, Nickel isotopes, Gamma rays
Abstract:	The article discusses the detection of gamma rays from radioactive nickel isotope 56 (56Ni) produced by the thermonuclear explosion of the type-Ia supernova SN2014J in the starburst galaxy M82. Topics include uncertainty about the physics that drives the explosion of type-Ia supernovae, an analysis of data from the Spectrometer (SPI) on the International Gamma Ray Astrophysics Laboratory (INTEGRAL) space mission, and the role of carbon-oxygen white dwarfs in supernova events.
