  The Jeans stability criterium for gravitational collapse is examined for the
case of an inert binary mixture in local equilibrium, neglectinq dissipative
effects. The corresponding transport equations are established using kinetic
theory within the Euler regime approximation. It is shown that the
corresponding dispertion relation is modified, yielding corrections to the
Jeans wave number. This formalism that can be generalized for several
interesting cases involving dissipation.
