General formulae for the periapsis shift of a quasi-circular orbit in static spherically symmetric spacetimes and the active gravitational mass density

Tomohiro Harada, Takahisa Igata, Hiromi Saida +1

We study the periapsis shift of a quasi-circular orbit in general static spherically symmetric spacetimes. We derive two formulae in full order with respect to the gravitational fi…

Periapsis shifts in dark matter distribution around a black hole

Takahisa Igata, Tomohiro Harada, Hiromi Saida +1

We consider the periapsis shifts of bound orbits of stars on static clouds around a black hole. The background spacetime is constructed from a Schwarzschild black hole surrounded b…
