论文摘要
使用地球方法和扰动方法，我们研究了时间周期性的球形对称引力场的光偏转。假设引力场的弱点，我们得出了确定领先顺序近似中偏转角的一般公式。该公式对于时间周期性和静态指标都是有效的。使用这些结果，我们计算通过具有对数电势的自我磨碎标量场的球形对称振荡分布的光射线的挠度角。事实证明，在这种情况下，挠度角不取决于领先顺序的时间。
Using the geodesic method and the perturbative approach, we study the deflection of light by time-periodic spherically symmetric gravitational fields. Assuming the weakness of the gravitational field, we derive general formulas that determine the deflection angle in the leading order approximation. The formulas are valid for both time-periodic and static metrics. Using these results, we calculate the deflection angle of a light ray passing through a spherically symmetric oscillating distribution of a self-gravitating scalar field with a logarithmic potential. It turned out that in this case the deflection angle does not depend on time in the leading order.
