不同的能量动量赝张量在双星PSR1913+16的引力辐射问题上的计算结果及分析

The Calculation Result Concerning the Problem of the Gravitational Radiationof the Double Star PSR1913+16 with Different Energy-Momentum Pseudo-Tensorsand its Analysis

摘要: 在二级近似精度内,各种不同形式的能量动量赝张量对于平面引力波只可能给出两种不同形式的结果,而关于双星PSR1913+16的周期的变化值所给出的结果是唯一的。进一步的分析表明,即使再构造新的能量动量赝张量,关于平面引力波也不可能给出更新的结果。

Abstract: In an accuracy up to the second order approximation, the results given for the plane gravitational waves by different energy-momentum pseudo-tensors can only be in two different forms, and the result given for the change of the period of the double star PSR 1913+16 is unique. Further analysis shows that it is impossible to give any new result for the plane gravitational waves even if other new energy mompntum pseudo tensors are constructed.
