脉冲星在B-P图上的演化途径

THE EVOLUTIONARY TRACK OF PULSARS IN FIGB—P

本文首先论述了决定脉冲星的演化参量和 B—P 图的意义,并用此参量绘出了脉冲星在 B—P 图上对于磁坊稳恒和衰减两种情况的不同演化途径。最后讨论了脉冲星在 B—P 图上演化过程明显分为四个区域。这些区域对脉冲星的演化是很有意义的。

First,the meanings determining the evolutionary parameters of Pulsarsand Fig B-P are outlined in this paper,and different evolutionary tracks of pulsars in the two cases for the constant and decay of the magnetic field are drawn by using the evolutio- nary parameters in Fig B-P.Lastly,the four regions devided into by the evolutionary process of pulsars are discussed in Fig B-P.These regions are very meaning in studying the evolution of pulsars.
