Scientific paper

The strong electric field at the surface of a strange star is discussed, and a self-consistent model is proposed to calculate its capability of supporting a "normal" nuclear material crust. We find that the electric field is already not able to support the crust even when the bottom density of the crust is still considerably lower than the neutron drip point, which means that it is not the neutron drip effect that limits the maximum crust density of a strange star. The maximum crust density is probably only about 8.3x10^10^g/cm^3^, so that a typical strange star (1.4Msun_) can not have a crust more massive than ~3.4x10^-6^Msun_. Considerable limitations are also presented for strange dwarfs.
