Some optical properties of rotating wormhole in Bopp-Podolsky electrodynamics

TL;DR

This paper investigates the optical properties of a rotating wormhole in Bopp-Podolsky electrodynamics, analyzing shadows and gravitational lensing to understand how parameters influence observable phenomena.

Contribution

It introduces a rotating wormhole model in Bopp-Podolsky electrodynamics and studies its optical signatures, including shadows and lensing, under various parameter conditions.

Findings

Shadows can be smooth or cuspy depending on parameters.

Most parameters significantly affect the shadows, except for parameter b when a or Q are small.

Strong gravitational lensing features like Einstein rings are analyzed in detail.

Abstract

In this work, we consider a static wormhole in Bopp-Podolsky electrodynamics and convert it into its rotating counterpart by reducing it into Morris-Thorne form. We further study the null geodesics and effective potential along with the shadows for inner and outer unstable orbits for specific choices of parameters. It is found that for some cases smooth shadow curves are formed and for a few cases, the shadows formed are cuspy. All parameters have a significant impact on the shadows except for the parameter $b$ when either $a$ or $Q$ are kept small. We also analyze the gravitational lensing in the strong regime, considering that the observer and the source are on opposite sides of the throat. For this situation, we explore in detail the behavior of the deflection angle, Einstein rings and lensing observables.
