Charged particles at the crust of compact stars may be ejected and
accelerated by the electric field generated due to the rotation of the
magnetized star. For neutron or hybrid stars, the negatively charged particles
are usually electrons, and the positively charged particles are mainly protons
and Iron. Whereas the existence of strange stars also includes the possibility
of ejection of strangelets from the star surface. The flux of such strangelets
emitted from all known pulsars is in the range of $10^9-10^{10}$ GeV.
Therefore, such massive strangelets can be one of the candidates for the
sources of the highest-energy cosmic rays that have still eluded us. Our model
proposes a possible origin of these ultra high energy cosmic rays.
