Abstract
The authors have recently published the book New Celestial Mechanics Mechanics, which presents the Theory of Dynamic Interactions (TDI), a conceptual proposal aimed at reconsidering the dynamics of rotating celestial bodies and, more generally, rotational mechanics.
Unlike the classical framework—based on the law of universal gravitation and its relativistic extensions—this approach introduces dynamic criteria applicable to systems subjected to non-coaxial rotations. It proposes that the interaction between intrinsic rotation and translational motion may generate closed trajectories and states of dynamic equilibrium.
TDI seeks to provide a unified description of the effect of non-coaxial torques on the trajectories of rigid bodies, including precession phenomena and possible stationary orbital states under specific dynamic conditions.
Although this is a non-conventional hypothesis, the proposed framework is intended to stimulate the theoretical and experimental analysis of complex rotational systems, with possible applications in satellite dynamics, aerospace engineering, and the modelling of accelerated physical systems.
