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…
Decoupling of kinematical time dilation and gravitational time dilation in particular geometries
A. Radosz, A. T. Augousti, K. Ostasiewicz
Two different forms of time dilation, namely, the kinematical time dilation of special relativity and gravitational red shift are coupled during observations of systems moving thro…
Doppler effect in Schwarzschild geometry
A. Radosz, A. T. Augousti, K. Ostasiewicz
The Doppler shift considered in general relativity involves mixed contributions of distinct, gravitational and kinematical origins and for most metrics or trajectories it takes a c…
