  The proper quantum plasma treatment of the electron gas in degenerate stars
such as white dwarfs provides an additional quantum contribution to the
electron pressure. The additional pressure term modifies the equation for
hydrostatic equilibrium, resulting in the quantum modified Lane-Emden equation
for polytropic equation of states. The additional pressure term also modifies
the expression for the limiting Chandrasekhar mass of white dwarfs. An
approximate solution is derived of the quantum modified Lane-Emden equation for
general polytropic indices, and it is demonstrated that the quantum corrections
reduce the standard Chandrasekhar mass and enhance the white dwarf radius by
negligibly small values only.
