Several recently discovered peculiar type Ia supernovae seem to demand an altogether new formation theory that might help explain the puzzling dissimilarities between them and the standard type Ia supernovae . The most striking aspect of the observational analysis is the necessity of invoking super-Chandrasekhar white dwarfs having masses \sim 2.1 - 2.8 M _ { \odot } , M _ { \odot } being the mass of Sun , as their most probable progenitors . Strongly magnetized white dwarfs having super-Chandrasekhar masses were already established to be potential candidates for the progenitors of peculiar type Ia supernovae . Owing to the Landau quantization of the underlying electron degenerate gas , theoretical results yielded the observationally inferred mass range . Here we sketch a possible evolutionary scenario by which super-Chandrasekhar white dwarfs could be formed by accretion on to a commonly observed magnetized white dwarf , invoking the phenomenon of flux freezing . This opens the multiple possible evolutions ending in supernova explosions of super-Chandrasekhar white dwarfs having masses within the range stated above . We point out that our proposal has observational support , like , the recent discovery of a large number of magnetized white dwarfs by SDSS .
