Abstract: (arXiv)
We made a detailed study of the properties of the electron layer near the quark surface of strange stars with strong (∼1014−1017\sim 10^{14}-10^{17}G) magnetic fields. The electrostatic potential and the electric field at the quark surface were calculated as functions of the magnetic field intensity of bare strange stars. Using an ultrastrong (B≥2.5×1016B\geq 2.5\times10^{16}G) magnetic field, we found that the distribution of electrons becomes an exponential function of radial distance, which is quite different in a magnetic field-free case. We also calculated the variation in gap width between the strange core and the normal nuclear crust for strange stars, which is due to magnetic field effect.
