Qualitative and quantitative features of orbits of massive particles and photons moving in Wyman geometry

G. Oliveira-Neto, G. F. Sousa

The Wyman's solution depends on two parameters, the mass $M$ and the scalar charge $\sigma$. If one fixes $M$ to a positive value, say $M_0$, and let ${\sigma }^2$ take values along the real li…
