SN 2007if exploded in a low metallicity dwarf galaxy. Due to its extreme brightness, red color, slow light curve and low expansion velocities, was deemed a Super-Chandrasekhar mass SN. Estimates of the nickel mass synthesized in the explosion from scaling laws and simple models were between 1.2 and 1.8 solar masses, inconsistent with the standard explosion of a Chandrasekhar mass white dwarf.
Comparison of the observational record of SN 2007if with those of normal Type Ia SNe suggests that the Super-Chandrasekhar scenario may not be correct. Even though the SN is very bright the post-maximum light curve shape is fairly similar to those of normal Type Ia SNe and, as the object evolves, the spectrum remarkably mutates into a normal Type Ia SNe. On the other hand, even though the scenarios leading to a Super-Chandrasekhar mass explosion must involve considerable degrees of asymmetry, VLT/FORS2 spectropolarimetry between 10 and 42 days after maximum show that the SN does not display continuum or line polarization.
I will review the observational record of SN 2007if, compare it with those of other SNe and conclude that scenarios other than the Super-Chandrasekhar one have to be considered in order to explain this SN.
