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…

Stability ranges of magnetic black holes and mirror (topological) stars in 5D gravity

Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova

We discuss static, spherically symmetric solutions to the 5D Einstein-Maxwell equations (belonging to wide classes of multidimensional solutions known at least from the 1990s) and…

The fine structure constant: a review of measurement results and possible space-time variations

K. A. Bronnikov, V. D. Ivashchuk, V. V. Khruschov

A brief description of the main methods for determining the fine structure constant is given. It is shown that the exact value of the fine structure constant is important for the n…

Overtones' outburst and Hawking evaporation of Kazakov-Solodukhin quantum corrected black hole

S. V. Bolokhov, K. A. Bronnikov, R. A. Konoplya

The Kazakov-Solodukhin black hole metric represents a spherically symmetric deformation of the Schwarzschild solution due to quantum-gravity corrections. Assuming the absence of no…

Alexei Starobinsky and wormhole physics

Kirill A. Bronnikov, Milena V. Skvortsova

Alexei Starobinsky is most famous for his great contribution to cosmology, but he has considerable achievements in other branches of gravitational physics and astrophysics, such as…

Magnetic mirror stars in five dimensions

Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova

We discuss a class of solutions of multidimensional gravity which are formally related to black-hole solutions but can observationally look like compact stars whose surface reflect…
