  The topic of magnetized super-Chandrasekhar white dwarfs is in the limelight,
particularly in the last few years, since our proposal of their existence. By
full-scale general relativistic magnetohydrodynamic (GRMHD) numerical analysis,
we confirm in this work the existence of stable, highly magnetized,
significantly super-Chandrasekhar white dwarfs with mass more than 3 solar
mass. While a poloidal field geometry renders the white dwarfs oblate, a
toroidal field makes them prolate retaining an overall quasi-spherical shape,
as speculated in our earlier work. These white dwarfs are expected to serve as
the progenitors of over-luminous type Ia supernovae.
