Deflection angles of light rays are affected by noncommutative effects.
Stability of circular orbits is modified in noncommutative spacetime.
Abstract
By considering particles as smeared objects, we investigate the effects of space noncommutativity on the orbits of particles in Schwarzschild spacetime. The effects of space noncommutativity on the value of the precession of the perihelion of particle orbit and deflection of light ray in Schwarzschild geometry are calculated and the stability of circular orbits is discussed.
