Padmanabhan, T.2012-02-292012-02-291989-09-15http://hdl.handle.net/11007/21We comment on the role played by a confining box in the energy dependence of the phase volume, g(E), of a system. This issue is related to the conservation of the total momentum and the position of the center of mass. A curious behavior of g(E) in the case of gravitationally bound binaries is pointed out.enAstrophysical JournalPhase spaceGravitational interactingNumerical methods-stars: binariesNote on the volume occupied in phase space by a system of gravitationally interacting particlesArticle
