Abstract
Over the last decade or so, we have been developing the possible existence of
highly magnetized white dwarfs with analytical stellar structure models. While
the primary aim was to explain the nature of the peculiar overluminous type Ia
supernovae, later on, these magnetized stars were found to have even wider
ranging implications including those for white dwarf pulsars, soft gamma-ray
repeaters and anomalous X-ray pulsars, as well as gravitational radiation. In
particular, we have explored in detail the mass-radius relations for these
magnetized stars and showed that they can be significantly different from the
Chandrasekhar predictions which essentially leads to a new super-Chandrasekhar
mass-limit. Recently, using the stellar evolution code STARS, we have
successfully modelled their formation and cooling evolution directly from the
magnetized main sequence progenitor stars. Here we briefly discuss all these
findings and conclude with their current status in the scientific community.
