The relativistic generalized vorticity tensor is constructed for the outer layer of the compact objects. The possibility of the existence of the double Beltrami-Bernoulli (BB) relaxed states/structures [1,2] is explored for the pulsar’s degenerate relativistic outer layer close to the surface. Theoretical formalism is based on the degenerate relativistic fluid equations taking into account the gravitational effects – the metric tensor is that of the Schwarzschild. The BB equilibrium is defined by two relativistic Beltrami conditions and Bernoulli equation for degenerate electron and positron fluids; as a result, Triple Beltrami states are obtained. For finding the illustrative numerical solutions of large-scale flows and magnetic fields equations are written in spherical coordinates and are expanded using spherical harmonic functions. Preliminary estimations for large-scale flow formation [3] in the pulsar outer layer close to the surface are performed. It is expected that the generated flows in compact object atmosphere will contribute to the matter and the energy of the large-scale jet; then, discovered effect can play an important role in the model of relativistic disk-jet structure formation around the compact objects like AGN and Pulsar. Constructed model can be applied for the exploration of observational features of relativistic jets.
