Uniqueness of the static vacuum asymptotically flat spacetimes with massive particle spheres
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
In this paper, we establish that a four-dimensional static vacuum asymptotically flat spacetime containing a massive particle sphere is isometric to the Schwarzschild spacetime. Ou…

Mass formulas for supergravity black holes with string singularities
Igor Bogush, Dmitri Gal'tsov, Gérard Clément
We extend the derivation of mass formulas for stationary axisymmetric asymptotically locally flat solutions with string singularities on the polar axis to general supergravity acti…

Constructing massive particles surfaces in static spacetimes
Igor Bogush, Kirill Kobialko, Dmitri Gal'tsov
The procedure for constructing the massive particle surfaces in static space-times is described in detail and the equivalence of the main results with the results of the geodesic a…
