Several recently discovered peculiar type Ia supernovae seem to demand analtogether new formation theory that might help explain the puzzlingdissimilarities between them and the standard type Ia supernovae. The moststriking aspect of the observational analysis is the necessity of invokingsuper-Chandrasekhar white dwarfs having masses ~ 2.1-2.8M_sun, M_sun being themass of Sun, as their most probable progenitors. Strongly magnetized whitedwarfs having super-Chandrasekhar masses were already established to bepotential candidates for the progenitors of peculiar type Ia supernovae. Owingto the Landau quantization of the underlying electron degenerate gas,theoretical results yielded the observationally inferred mass range. Here wesketch a possible evolutionary scenario by which super-Chandrasekhar whitedwarfs could be formed by accretion on to a commonly observed magnetized whitedwarf, invoking the phenomenon of flux freezing. This opens the multiplepossible evolutions ending in supernova explosions of super-Chandrasekhar whitedwarfs having masses within the range stated above. We point out that ourproposal has observational support, like, the recent discovery of a largenumber of magnetized white dwarfs by SDSS.
