论文摘要
遵循最近的方法，在BOPP--Podolsky电动力学中介绍了弯曲空间中的重力场方程，在这种情况下，我们获得了近似且球形对称的虫洞溶液。在时空几何和径向电场中，将计算进行到线性近似。该解决方案提出了来自模型拉格朗日的新参数。通过使用射手座A*的阴影半径来限制这样的参数，该事件地平线望远镜协作最近揭示了这种参数。值得注意的是，当将其阴影与射手座A*阴影相提并论时，这里呈现的虫洞是可行的。
Following a recent approach in which the gravitational field equations in curved spacetimes were presented in the Bopp--Podolsky electrodynamics, we obtained an approximate and spherically symmetric wormhole solution in this context. The calculations were carried out up to the linear approximation in both the spacetime geometry and the radial electric field. The solution presents a new parameter that comes from the Lagrangian of the model. Such a parameter was constrained by using the shadow radius of Sagittarius A*, recently revealed by the Event Horizon Telescope Collaboration. Remarkably, the wormhole presented here is viable when its shadow is compared to the Sagittarius A* shadow.
