The Luminous and Carbon-rich Supernova 2006gz: A Double Degenerate Merger? Academic Article uri icon


  • Spectra and light curves of SN 2006gz show the strongest signature of unburned carbon and one of the slowest fading light curves ever seen in a Type Ia event [m15(B) = 0.69 0.04]. The early-time Si ii velocity is low, implying it was slowed by an envelope of unburned material. Our best estimate of the luminosity implies MV = -19.74 and the production of 1.2 Mof 56Ni. This suggests a super-Chandrasekhar mass progenitor. A double degenerate merger is consistent with these observations. 2007. The American Astronomical Society. All rights reserved.
