摘要

用一种简单的微扰方法导出了加速Fisher-Janis-Newman-Winicour （FJNW）度量的精确形式。我们还认为，通过使用Buchdahl变换，可以获得相同的加速FJNW度量。我们研究了加速FJNW度量的奇异性，并研究了它们对该时空的全局和局部结构的影响。我们还研究了圆轨道的测地线和稳定性。

Accelerating FJNW metric

We derive exact form of accelerating Fisher-Janis-Newman-Winicour (FJNW) metric by a simple perturbative method. We also argue that by using Buchdahl transformations one can obtain the same accelerating FJNW metric. We investigate singularities of the accelerating FJNW metric and study their effects on global and local structures of this spacetime. We also study geodesics and stability of circular orbits.
