Query: Landau quantization and mass-radius relation of magnetized White Dwarfs
  in general relativity   Recently, several white dwarfs have been proposed with masses significantly
above the Chandrasekhar limit, known as Super-Chandrasekhar White Dwarfs, to
account for the overluminous Type Ia supernovae. In the present work, Equation
of State of a completely degenerate relativistic electron gas in magnetic field
based on Landau quantization of charged particles in a magnetic field is
developed. The mass-radius relations for magnetized White Dwarfs are obtained
by solving the Tolman-Oppenheimer-Volkoff equations. The effects of the
magnetic energy density and pressure contributed by a density-dependent
magnetic field are treated properly to find the stability configurations of
realistic magnetic White Dwarf stars.
