Overview

Analytic characterization of black holes shows how deformation impacts thermodynamics and accretion performance.

Key Points

  • The research aims to analyze regular, asymptotically flat black holes within a quasi-topological gravity framework.
  • Analytic and numerical characterization of black holes using a four-dimensional non-polynomial quasi-topological model.
  • Analysis of key phenomena including Hawking temperature, shadow radius, and photon-orbit stability across parameter domains.
  • Study of Novikov-Thorne thin-disk accretion dynamics, deriving effective temperature profiles and luminosity scaling.
  • Increasing the deformation parameter reduces the Hawking temperature and shadow size while enhancing binding efficiency and luminosity.
  • Higher curvature corrections lead to a deviation from Schwarzschild behavior, with changes in observable characteristics.
  • Results indicate a mapping of horizon structure with thermodynamic and optical signatures in black hole dynamics.
