Charged black holes in generalized dilaton-axion gravity (original) (raw)

This work presents new black hole solutions within the framework of generalized dilaton-axion gravity, specifically focusing on Einstein-Maxwell-scalar field systems motivated by low energy string theory. The study explores the conditions necessary for these solutions to emerge, highlighting the implications and potential astrophysical consequences such as gravitational lensing and particle geodesics. Major findings include the characterization of these black holes and discussions on their thermodynamic properties, with indications of future work aimed at investigating rotating black holes and their observational impacts.
