We show that in some ranges of the charge parameters charged stringy black hole metric can provide the same ISCO as in the case of the well known Kerr metric for the test particles. Based on the idea that charge parameters of the stringy black hole metric can provide the same ISCO for the test particles it would be difficult to distinguish these two metrics if one relies on the observations...
The regularized four-dimensional Einstein-Gauss-Bonnet model has been recently proposed in [D. Glavan and C. Lin, Phys. Rev. Lett. \textbf{124}, 081301 (2020)] whose formulation is different of the Einstein theory, allowing us to bypass the Lovelock theorem. The action is formulated in higher dimensions (D>4) by adding the Gauss-Bonnet correction to the conventional Einstein-Hilbert action...
