Regular magnetic black holes with anti-de Sitter cores in scalar-tensor gravity: axial stability and radial instability
Rustam Ibadov, Najibullokhon Shukurullokhon
We construct static, asymptotically flat regular black holes in Einstein-frame scalar--tensor gravity, sourced by a canonical scalar coupled to magnetic nonlinear electrodynamics.…

Regular spherically symmetric solutions in General Relativity and scalar-tensor gravity coupled to nonlinear electrodynamics and their stability
Rustam Ibadov, Najibullokhon Shukurullokhon
We investigate the geometric, dynamical, and thermodynamic properties of a novel class of regular black holes in scalar-tensor gravity non-minimally coupled to nonlinear electrodyn…

Nonlinear electrodynamics and stability of spherically symmetric space-times in scalar-tensor gravity
Kirill A. Bronnikov, Rustam Ibadov, Feruza Y. Shaymanova +1
We study linear perturbations of static, spherically symmetric solutions of scalar-tensor theories (STT) of gravity from the Bergmann-Wagoner-Nordtvedt class, sourced by nonlinear…
