摘要

脉冲星微脉冲宽度与自转周期之间的线性关系与中子星表面存在的物理长度 L 以及观测者穿越极冠的弧线是一致的。在离子-质子模型中，能够支持不稳定的双束朗缪尔模式临界增长率的最小表面区域的宽度就是无线电发射源。

On the origin of the quasi-periodic micro-pulses observed in the radio-frequency emission of some neutron stars

The linear relationship between pulsar micro-pulse widths and rotation period is consistent with the existence of a physical length L on the neutron-star surface and seen on the observer arc of transit across the polar cap. Within the ion-proton model it is the width of the minimum area of surface that can support the critical growth rate of the unstable two-beam Langmuir mode that is the source of the radio emission.

期刊介绍： For papers that merit urgent publication, MNRAS Letters, the online section of Monthly Notices of the Royal Astronomical Society, publishes short, topical and significant research in all fields of astronomy. Letters should be self-contained and describe the results of an original study whose rapid publication might be expected to have a significant influence on the subsequent development of research in the associated subject area. The 5-page limit must be respected. Authors are required to state their reasons for seeking publication in the form of a Letter when submitting their manuscript.
