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…

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…

The geometry of massive particle surfaces
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We propose a generalization of Claudel, Virbhadra, and Ellis photon surfaces to the case of massive charged particles, considering a timelike hypersurface such that any worldline o…
