The classical phenomenon of the redshift of light in a static gravitational potential, usually called the gravitational redshift, is described in the literature essentially in two ways: On the one hand, the phenomenon is explained through the behavior of clocks which run faster the higher they are located in the potential, whereas the energy and frequency of the propagating photon do not change...

Abstract The objective of this paper is to study the tidally locked 3:2 spin–orbit resonance Mercury around Sun. In order achieve goal, effective potential energy that determines spinning motion an ellipsoidal planet its axis considered. By studying rotational orbiting a spherical star on elliptic orbit with fixed eccentricity and semi-major axis, it shown system presents infinite number metast...
