内容記述 | The electron-positron pair annihilation effects on the surface ion cyclotron wave are investigated in magnetized electron-positron-ion plasmas in atmospheres of neutron stars. The dispersion relation of the surface ion cyclotron wave is obtained by the specular reflection boundary condition with the plasma dielectric function. It is shown that the high- and low-frequency modes of the surface ion cyclotron wave could be existed in electron-positron-ion plasmas. For the high-frequency mode, the pair annihilation enhances the wave frequency in large wave number domains. However, the pair annihilation effects are found to be negligible for the low-frequency mode. It is also found that an increase of the electron temperature or a decrease of the positron temperature strongly suppresses the wave frequency. It is shown that an increase of the magnetic field strongly enhances the wave frequency. | |||||||||
