Minimal geometric deformation of Yang-Mills-Dirac stellar configurations

The method of minimal geometric deformation (MGD) is used to derive static, strongly gravitating, spherically symmetric, compact stellar distributions that are solutions of the Yang-Mills-Einstein-Dirac coupled field equations on fluid membranes with finite tension. Their solutions characterize MGD Yang-Mills-Dirac stars, whose mass has order of the Chandrasekhar mass, once the range of both the fermionic self-interaction and the Yang-Mills coupling constants is suitably chosen. Physical features of MGD Yang-Mills-Dirac stars are then discussed and their Arnowitt-Deser-Misner masses are derived, as a function of the fermion coupling constant, the finite brane tension, and the Yang-Mills running parameter.
