Covering both astronomical and geophysical perspectives, this book describes changes in the Earth's orientation, specifically precession and nutation, and how they are observed and computed in terms of tidal forcing and models of the Earth's interior. Following an introduction to key concepts and elementary geodetic theory, the book describes how precise measurements of the Earth's orientation are made using observations of extra-galactic radio-sources by Very Long Baseline Interferometry techniques. It demonstrates how models are used to accurately pinpoint the location and orientation of the Earth with reference to the stars and how to determine variations in its rotation speed. A theoretical framework is also presented that describes the role played by the structure and properties of the Earth's deep interior. Incorporating suggestions for future developments in nutation theory for the next generation models, this book is ideal for advanced-level students and researchers in solid Earth geophysics, planetary science and astronomy.

Les interactions de marée au sein de systèmes binaires formés par deux étoiles en orbite serrée engendrent une série de phénomènes qui peuvent affecter l'orbite elle-même, mais aussi l'évolution des étoiles qui composent la binaire. Dans la première partie de ce travail, nous étudions l’influence des interactions de marée sur le mouvement des apsides dans la binaire massive HD 152218. Nous déterminons les paramètres absolus de la binaire à partir d'une analyse de sa courbe de lumière et examinons l’évolution de la constante de structure interne des étoiles sur base de modèles de structure interne d’étoiles. Nous établissons la méthodologie nécessaire à l’interprétation du mouvement des apsides. Nous comparons les résultats théoriques obtenus avec notre détermination observationnelle du taux de mouvement des apsides de la binaire. A partir des résultats obtenus, nous discutons de l’âge des étoiles de cette binaire. Dans la seconde partie de ce travail, nous étudions l’influence des interactions de marée sur le mouvement de précession des axes de rotation des étoiles des binaires massives HD 152218 et HD 191612. Nous présentons les particularités de la binaire HD 191612 et développons le formalisme nécessaire à l’étude de la précession.

The Theory of the Top: Volume I. Introduction to the Kinematics and Kinetics of the Top is the first of a series of four self-contained English translations of the classic and definitive treatment of rigid body motion. Key features: * Complete and unabridged presentation with recent advances and additional notes * Annotations by the translators provide insights into the nature of science and mathematics in the late 19th century * Each volume interweaves theory and applications Volume I focuses on providing fundamental background material and basic theoretical concepts. The Theory of the Top was originally presented by Felix Klein as an 1895 lecture at Göttingen University that was broadened in scope and clarified as a result of collaboration with Arnold Sommerfeld. Graduate students and researchers interested in theoretical and applied mechanics will find this a thorough and insightful account. Other volumes in this series include Development of the Theory for the Heavy Symmetric Top, Perturbations: Astronomical and Geophysical Applications, and Technical Applications of the Theory of the Top.
