Trajectories of the local centroids in a two-component stellar system near the sun

In a stellar system in nonsteady states and according to Chandrasekhar's axially-symmetric model, the general trajectory of a local centroid is determined. In the neighbourhood of the Sun, a two-component stellar system is adopted to explain the kinematic behaviour of the stellar samples. Depending on the kinematic parameters of each subsystem, the trajectories of every local subcentroid are shown.Life is long for the wise stars but short for the giddy ones Some Seneca-like words about De breviate vitaePaper presented at the 11th European Regional Astronomical Meetings of the IAU on New Windows to the Universe, held 3–8 July, 1989, Tenerife, Canary Islands, Spain.
