A Further Study of Relative Longitude Shift of Pulsar Beams |
| |
| Abstract: | It is of great importance to study pulsar beam shape if we are concerned with emission theories and pulsar birth rate.Both observations and the ICS model show that different emission components are emitted from different heights.The relative longitude phase shifts due to different heights of the emission components and the toridal velocity of the electrons are considered in this paper.Several pos-sible observational effects arising from the phase shift are presented.The emission beams may not have circular cross section although the emission region may be symmetric with respect to the magnetic axis. |
