Query: One possible solution of peculiar type Ia supernovae explosions caused
  by a charged white dwarf   Recent astrophysics observation reveals the existence of some super luminous
type Ia supernovae. One natural explanation of such a peculiar phenomenon is to
require the progenitor of such a supernova to be a highly super-Chandrasekhar
mass white dwarf. Along this line, in this paper, we propose a possible
mechanism to explain this phenomenon based on a charged white dwarf. In
particular, by choosing suitable new variables and a representative charge
distribution, an analytic solution is obtained. The stability issue is also
discussed, remarkably, it turns out that the charged white dwarf configuration
can be dynamically stable. Moreover, we investigate the general relativistic
effects and it is shown that the general relativistic effects can be negligible
when the mass of the charged white dwarf is below about $3M_\odot$.
