  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 ~ 2.1-2.8M_sun, M_sun 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.
