Description

We investigate the weak gravitational lensing and black hole shadows properties in the vicinity of static regular Frolov black hole.We investigate the bending of light in weak field regimes. The black hole shadow is studied in detail, with constraints on its parameters derived from observational data of the EHT collaboration. Further, we examine the shadow images under a spherically symmetric accretion flow and compute the energy emission rate to understand the black hole radiation characteristics. The obtained results demonstrate how the Frolov black hole difeeres from well-know black hole solutions in General Relativity. This study provides new insight into the impact of modified regular black hole solutions on observational signatures. The fining have significant implication for future astrophysical observations and the testing of alternative gravity theories.
