| 摘 要： | In this paper, the propagation of x-ray bursts in the magnetoplasma of pulsar magnetosphere is discussed. The electromagnetic interaction between x-ray bursts and magnetoplasma is described as some geometry. The electromagnetic effects of surface superstrong magnetic field and dynamic effects of outflowing magnetoplasma of pulsars are treated as an optical metric. The Gordon metric is introduced to represent the gravitational metric and optical metric. So the propagation of x-ray bursts in magnetoplasma of pulsars can be described as x-ray bursts transmitting in an effective space characterized by Gordon metric. The modification of gravitational redshift, attributed to the flowing magnetoplasma of pulsars, is obtained and it is shown that the modification is of redshift and can reach the same magnitude as the gravitational redshift for ordinary pulsars.

| Abstract: | In this paper, the propagation of x-ray bursts
in the magnetoplasma of pulsar magnetosphere is discussed. The electromagnetic
interaction between x-ray bursts and magnetoplasma is described as some geometry.
The electromagnetic effects of surface superstrong magnetic
field and dynamic effects of outflowing magnetoplasma of pulsars are
treated as an optical metric. The Gordon metric is introduced to
represent the gravitational metric and optical metric. So the
propagation of x-ray bursts in magnetoplasma of pulsars can be
described as x-ray bursts transmitting in an effective space
characterized by Gordon metric. The modification of gravitational
redshift, attributed to the flowing magnetoplasma of pulsars, is
obtained and it is shown that the modification is of redshift and can
reach the same magnitude as the gravitational redshift for ordinary
pulsars. |
