Spin-Orbit Synchronization and Singular Perturbation Theory
Clodoaldo Ragazzo, Lucas Ruiz dos Santos
In this study, we formulate a set of differential equations for a binary system to describe the secular-tidal evolution of orbital elements, rotational dynamics, and deformation (f…

Tidal Evolution and Spin-Orbit Dynamics: The Critical Role of Rheology
Clodoaldo Ragazzo, Lucas Ruiz dos Santos
This study analyzes secular dynamics using averaged equations that detail tidal effects on the motion of two extended bodies in Keplerian orbits. It introduces formulas for energy…

Andrade rheology in time-domain. Application to Enceladus' dissipation of energy due to forced libration
Yeva Gevorgyan, Gwenaël Boué, Clodoaldo Ragazzo +2
The main purpose of this work is to present a time-domain implementation of the Andrade rheology, instead of the traditional expansion in terms of a Fourier series of the tidal pot…
