The Local and Global Geometrical Aspects of the Twin Paradox in Static Spacetimes: II. Reissner--Nordstr\"om and Ultrastatic Metrics
2014
Acta Physica Polonica B
This is a consecutive paper on the timelike geodesic structure of static spherically symmetric spacetimes. First we show that for a stable circular orbit (if it exists) in any of these spacetimes all the infinitesimally close to it timelike geodesics constructed with the aid of the general geodesic deviation vector have the same length between a pair of conjugate points. In Reissner--Nordström black hole metric we explicitly find the Jacobi fields on the radial geodesics and show that they are
