Gravitomagnetic Effects on Collective Plasma Oscillations in Compact Stars

The effects of gravitomagnetic force on plasma oscillations are investigated using the kinetic theory of homogeneous electrically neutral plasma in the absence of external electric or magnetic field. The random phase assumption is employed neglecting the thermal motion of the electrons with respect to a fixed ion background. It is found that the gravitomagnetic force reduces the characteristic frequency of the plasma thus enhancing the refractive index of the medium. The estimates for the predicted effects are given for a typical white dwarf, pulsar, and neutron star.

数学物理第12届地区会议文集

2006年3月27～4月1日，巴基斯坦国家物理中心（NCP）在巴基斯坦首都伊斯兰堡举行了第12届地区数学物理会议，本书是这届会议的论文汇集。该会议起始于1986年，由伊朗、巴基斯坦和土耳其三国物理学家共同发起举办，主要由上述三国学者参加，以后逐渐扩大到中亚独联体国家及印度、孟加拉等国，旨在交流有关成果，探讨共同感兴趣的学术问题。
