[en] We investigate the orbits of metal-poor stars in a modified Ostriker and Caldwell Galactic mass model. These stars have well-determined spectroscopic abundances and our objective is to search for a relationship between these abundances and the characteristics of orbits such as excentricity, chaoticity...
