  The method of geometric deformation (MGD) is here employed to study compact
stellar configurations, which are solutions of the effective Einstein-Dirac
coupled field equations on fluid branes. Non-linear, self-interacting,
fermionic fields are then employed to derive MGD Dirac stars, whose properties
are analyzed and discussed. The MGD Dirac star maximal mass is shown to
increase as an specific function of the spinor self-interaction coupling
constant, in a realistic model involving the most strict phenomenological
current bounds for the brane tension.
