Consider an hydrostatic self-gravitating sphere. The gravitational field is generated by 2 components: a visible (o) and an unseen (x). The resolution of the equations yields global quantities such as the mass (observed, unseen or total) of matter in the configuration Mo,x,t the ratio of unseen mass to visible one R = Mx/Mo, the mean quadratic velocity computed on the configuration V2o,x, Cv=V2x/V2o the relative concentration indicator of kinetic energy, and the relative concentration indicators of x-matter and x-potentiel energy Ci and Cx.
