| 摘 要： | 本文利用摄动方法研究引力辐射阻尼对双星轨道要素产生的影响。这种影响导致双星系统的瓦解,特别轨道长轴、偏心率和公转周期不仅有周期变化,也有长期变化,但对近星点进动只有周期变化。最后利用所推的结果对三颗双星(Y cyg,PSR2303+24,PSR1913+16)的轨道要素变化产生的周期项和长期项做了数值估计,并同广义相对论效应做了比较。

| Abstract: | In this paper the effect of gravitational radiation damping on the variation of the orbital elements of binary system is studied using the method of perturbation. This effect results in both the secular and periodic variation of the semimajor axis and the eccentricity, however, the longitude of periastron exhibits no secular variation, but only periodic variation In addition, the deduced expression is applied to calculate the variation of secular and periodic terms of the orbital elements of binary system, Y cyg, PSR 1913 + 16 and PSR 2303 + 24, and the obtained results are discussed and compared with the relativistic effects. |
