  We investigate charge densities around the vortex cores of an s-wave and a
chiral p-wave superconductor (SC) in two dimension within quasiclassical
theory. We consider contributions of particle-hole asymmetry through gradient
expansions in first order of a quasiclassical parameter using augmented
quasiclassical theory. The chiral p-wave SC has two inequivalent vortices: one
is charged and the other is uncharged on the basis of Bogoliubov--de Gennes
(BdG) equation. We explain this qualitatively distinct charges also by the
augmented quasiclassical theory. In addition, we find that much larger charge
is induced for the charged vortex of the chiral p-wave SC compared with the
vortex of the s-wave SC in the clean system. We also confirm this enhancement
through quantitative comparison with results based on the BdG theory. We also
study effects of Born-type impurities using self-energy formalism and find that
the larger charge density is rather suppressed in contrast to the s-wave's one.
Furthermore we study the local density of states as another equilibrium
property of particle-hole asymmetry.
