引力辐射阻尼对双星轨道要素变化的影响——对过近星点时刻的影响

在文献［１］研究的基础上对双星引力辐射阻尼的效应又做了进一步研究．首先给出文献［１］的主要结果及其更正，然后利用文献［１］的结果又给出引力辐射阻尼对双星过近星点时刻的影响。结果表明，引力辐射阻尼对双星过近星点时刻不仅产生周期变化的效应，而且还产生长期变化的效应，这后者的效应使得双星过近星点时刻提前。最后利用所推出的结果对三颗双星（Ｙ Ｃｙｇ，ＰＳＲ２３０２＋２４．ＰＳＲＩ９１３＋１６）做了数值的长期效应的计算。关键词：

EFFECT OF GRAVITATIONAL RADIATION DAMPING ON THE VARIATION OF THE ORBITAL ELEMENTS OF BINARY SYSTEMS——THE EFFECT ON THE TIME OF PASSING PERIGEE OF BINARY STAR

The effect of gravitational radiation damping on the variation of the orbital elements of binary system is studied further base on our previous work[1].The result and correction for the previous paper are presented. The effect of gravitational damping on the time of passing perigee of binary star is given. The result shows clearly that the gravitational damping results in both the periodic and secular variation of the time of passing perigee, that is, the time of passing perigee moves up in every revolution. The numerical estimation for the effect on the variation of the time of passing perigee of binary stars, Y Cyg, PSR 1913+16 and PSR 2303+24 been made.
