Relativistic aspects of rotational motion of celestial bodies

The Motion of Celestial Bodies

The history of celestial mechanics is first briefly surveyed, identifying the major contributors and their contributions. The Ptolemaic and Copernican world models, Kepler’s laws of planetary motion and Newton’s laws of universal gravity are presented. It is shown that the orbit of a body moving under the gravitational attraction of another body can be represented by a conic section. The six or...

Celestial Mechanics of Elastic Bodies

We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their center of mass or strictly static configurations.

Effects of Rotational Motion in Robotic Needle Insertion

Background: Robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations.Objective: In this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diagram. Non-homogenous camel liver can be exploite...

A Modification To The Gaseous Pressure Gradients In Spherical Celestial Bodies: Effects Of The Thermal Motion

The atmospherical pressure gradients of spherical celestial bodies are very important in astrophysics and other related areas. The classical form of the gradient in a gravitation-dominated celestial body: dp dR = − R ρ has been widely adopted for quit a long time. But, in this form, a factor has been neglected: the centrifugal force that due to the thermal motion of gaseous particles in a centr...
