毫秒脉冲星的高能辐射

The high-energy emission from millisecond pulsars

  • 摘要: 根据自恰毫秒脉冲星磁层外隙模型讨论毫秒脉冲星的高能辐射机制.其中X射线由2个热成分和1个幂律成分组成,γ射线由外隙粒子同步-曲率辐射产生.在此基础上,理论计算了11颗X射线波段及其他39颗在射电波段观测到的毫秒脉冲星,所得理论与观测符合较好,表明该模型能较好地解释毫秒脉冲星的高能辐射机制.

     

    Abstract: The significant progresses on both the theoretical and observational researches on millisecond pulsars(MSPs) have been obtained in recent years.The high-energy emission of MSPs is discussed.The backflow of charged particles from the outer gap produce the X-rays,which consist of two thermal components and one powerlaw component.The gamma-rays are produced in the outer gap through synchro-curvature radiation.Furthermore,the luminosities of 11 MSPs which have been observed in the X-ray band and 39 MSPs which have been observed only in the radio bandtemporarily are calculated.The theoretical results are good consistent with the observations.
