EVOLUTION DYNAMIQUE DES ASTEROIDES QUI CROISENT L'ORBITE DE LA TERRE by Patrick Michel( Book )

2 editions published in 1997 in French and held by 5 WorldCat member libraries worldwide

CETTE THESE PRESENTE L'ETUDE DES EVOLUTIONS DYNAMIQUES DES ASTEROIDES QUI CROISENT L'ORBITE DE LA TERRE, APPELES NEAS (SELON L'APPELLATION ANGLAISE NEAR-EARTH ASTEROIDS) ET PLUS PARTICULIEREMENT DE CEUX DONT LE DEMI-GRAND AXE ORBITAL A EST INFERIEUR A 2 UA. LES INTEGRATIONS NUMERIQUES SUR PLUSIEURS MILLIONS D'ANNEES D'ORBITES DE NEAS AVEC UN INTEGRATEUR APPROPRIE MONTRENT QUE LES RENCONTRES PROCHES AVEC LES PLANETES NE SONT PAS LES SEULES SOURCES DE CHANGEMENT DRASTIQUE DE LEURS ELEMENTS ORBITAUX. D'AUTRES MECANISMES DYNAMIQUES PEUVENT EN EFFET SE PRODUIRE ET JOUER UN ROLE MAJEUR AU COURS DES EVOLUTIONS DE CES OBJETS. LES RESONANCES DE MOYEN MOUVEMENT AVEC LES PLANETES TELLURIQUES ET LA RESONANCE DE KOZAI FOURNISSENT DES MECANISMES DE PROTECTION CONTRE LES RENCONTRES AVEC LES PLANETES, AUGMENTANT AINSI LA DUREE DE VIE DES OBJETS QUI LES SUBISSENT. LES RESONANCES SECULAIRES PERMETTENT LE TRANSPORT DES ORBITES DANS DIFFERENTES REGIONS DE L'ESPACE DES PHASES. ELLES PEUVENT AINSI FAIRE PASSER UN NEA D'UNE REGION QUASI-STABLE VERS UNE REGION CROISANT UNE PLANETE. UNE METHODE SEMI-ANALYTIQUE UTILISANT LE FORMALISME HAMILTONIEN EST ENSUITE DEVELOPPEE. LA PREMIERE LOCALISATION DE TOUTES LES RESONANCES SECULAIRES LINEAIRES DANS LA REGION A < 2 UA EST ALORS OBTENUE. TOUTES CES RESONANCES SONT PRESENTES ET CERTAINS CAS DE RECOUVREMENT APPARAISSENT. L'INTRODUCTION DE VARIABLES ANGLE-ACTION APPROPRIEES PERMET ENSUITE D'OBTENIR DES RESULTATS QUANTITATIFS SUR LEURS EFFETS DANS CETTE REGION ET CONFIRME LEUR EFFICACITE. ENFIN, UN MODELE A DEUX RESONANCES EST DEVELOPPE ET MONTRE QUE LES INTERACTIONS ENTRE DEUX RESONANCES PEUVENT CONDUIRE A DU CHAOS A GRANDE ECHELLE. AINSI, LA REGION A < 2 UA OU EVOLUENT LA PLUPART DES NEAS EST RICHE ET COMPLEXE DU POINT DE VUE DE LA DYNAMIQUE. LA VARIETE DES EVOLUTIONS EST SI GRANDE QU'UN SEUL CAS DE FIGURE NE PEUT REPRESENTER L'ENSEMBLE DES POSSIBILITES. LES NEAS SONT EN EFFET AFFECTES PAR DES MECANISMES DYNAMIQUES DIFFERENTS DE L'UN A L'AUTRE CONDUISANT AUSSI A DES TEMPS DE VIE DYNAMIQUES DIFFERENTS. PAR CONSEQUENT, UNE METHODE D'ETUDE NE CONSIDERANT QUE LES EFFETS DES RENCONTRES PROCHES AVEC LES PLANETES N'EST PAS SUFFISANTE CAR L'ENSEMBLE DES MECANISMES DYNAMIQUES NOMBREUX ET EFFICACES DANS CETTE REGION DOIT ETRE PRIS EN COMPTE

Contribution à l'étude de la dynamique des comètes by Marc Fouchard( Book )

Cometary dynamics is a complex subject, characterized by various regimes of motion. In order to model cometary dynamics in a proper way, it is important to identify clearly these different regimes. This is why a fast Lyapunov indicator in the frame of gravitational continuous dynamical systems was first developed. The conditions under which a well known, published Monte Carlo method can be applied to the dynamics of Jupiter family comets were then studied. Although a number of improvements were introduced in the model, it turned out that the dynamics of Jupiter family comets is not amenable to Monte Carlo modelling du to the presence of many mean motion resonances with Jupiter. In this thesis a model which is able to reproduce effects of the galactic tide on the Oort cloud comet using a mapping is developed. This mapping correctly reproduces the dynamics of comets with semi-major axis ≤ 30000 AU, and is 500 times faster than the use of direct numerical integrations
