Spectral modelling of the 'super-Chandrasekhar' Type Ia SN 2009dc - testing a 2 M⊙ white dwarf explosion model and alternatives

Hachinger, S; Mazzali, Paolo A; Taubenberger, Stefano; Fink, M; Pakmor, R; Hillebrandt, Wolfgang; Seitenzahl, Ivo


Extremely luminous, ‘super-Chandrasekhar’ (SC) Type Ia Supernovae (SNe Ia) are as yet an unexplained phenomenon. We analyse a well-observed SN of this class, SN 2009dc, by modelling its photospheric spectra with a spectral synthesis code, using the technique of ‘Abundance Tomography’. We present spectral models based on different density profiles, corresponding to different explosion scenarios, and discuss their consistency. First, we use a density structure of a simulated explosion of a 2 M⊙...[Show more]
