| 摘 要： | 本文作者首次发现了EXO 2030+375的回旋吸收线迹象.这是迄今唯一一个同时有用回旋吸收线直接测量的磁场数据和用吸积演化方法间接测量的中子星磁矩数据的X射线脉冲星.两种测量方法的结果有很大差别,本文提出了可能导致这种差别的物理机制.

| Abstract: | Evidence of a transient cyclotron absorption line was observed in EXO2030+375 for the first time. This source is the best one of X-ray pulsars with both direct measurement of magnetic field by applying the result of cyclotron absorption measurement and indirect measurement of magnetic torque by applying accretion torque theory. The results obtained from these two methods are quit different. The possible mechanism leading to the differences were suggested |
