Turning points of massive particles in Schwarzschild geometry
J. Polonyi, A. Radosz, A. Siwek +1
The stable geodesics in Schwarzschild geometry can not approach the center closer than the radius of the photon sphere, 3/2 times the Schwarzschild radius. In other words, massive…

The Doppler shift in a Schwarzschild spacetime
A. Radosz, A. T. Augousti, K. Ostasiewicz
We demonstrate that in the case of Schwarzschild spacetime the Doppler shift is partially factorized into terms representing relativistic, kinematical and the gravitational contrib…
