Viable wormhole solution in Bopp-Podolsky electrodynamics

Understand

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.
