Particle motion, shadows and thermodynamics of regular black hole in pure gravity

This paper investigates the thermodynamic behaviors and optical properties of regular black holes within pure gravity theories, notable for their absence of singularities. Using both analytical and numerical methods, we analyze the thermodynamics to identify stability and phase transitions, and explore the particle dynamics behavior of regular black holes. We analyze the particle dynamics properties by investigating the effective potential, energy density, angular momentum, ISCO , photon, and shadow radius. We analyze the thermal features by exploring the mass, temperature, specific heat, and Gibbs free energy. Our findings demonstrate that regular black holes exhibit distinct behaviors from traditional singular black holes, providing valuable insights into black hole physics and general relativity. This study suggests new directions for future research in fundamental gravitational theories.
