The, structure is presented in the space a (semi-major axis)versus e (eccentricity)in terms of chaotic and regular regions associated to mean motion resonances. The regular regions defined as being those due to the maximum amplitude of libration around periodic orbits and those due to quasi-periodic orbits of circulation. The remaining regions are chaotics. The structure are derived from Poincaré surfaces of section. The results show remarkable differences depending on the mass ratio. As expected, the width of libration regions due to resonances is wider for u, than for un., However , there are more resonances evident in the structure for uN than for u. The results reveal that resonances of order higher than one play an important role in the structure of the phase space for un. %@secondarydate 20021213 %E Winter, Othon Cabo, %E Prado, Antonio Fernando Bertachini de Almeida., %T A comparasion between the phase space structures of the three-body problem for different mass ratio %S Advances in space dynamics 2: applications in astronomy %@format ISBN 85-17-00005-6 %@secondarytype PRE LN %K ENGENHARIA E TECNOLOGIA ESPACIAL, three-body problem, chaos, resonances, phase space. %B Advances in space dynamics 2: applications in astronomy %@usergroup administrator %@group DMC-INPE-MCT-BR %C São José dos Campos %@secondarykey INPE-9540-PRE/5193 %F 10468 %2 sid.inpe.br/iris@1905/2005/08.04.02.09.27 %@versiontype publisher %I INPE %P 56-62 %4 sid.inpe.br/iris@1905/2005/08.04.02.09 %D 2002 %@documentstage not transferred %A Celestino, Cláudia Celeste, %A Wintyer, Othon Cabo, %@area ETES %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S}
