The theoretical foresight of lifelong partners for Sgr A*

Abstract: [Objective] Reveal that the bright companionship of Sgr A* is not an accretion disk, but a self-organizing magnetized plasma circulation generated by its own "selective phagocyt-vomiting" mechanism.
 [Methods] Based on the plasma particle-level Lorentz decoupling and motion polarization effect, it is proposed that black holes screen particles through intrinsic phagocytration field strength (Z’s-Er) during the high accretion period, and the light material spiting out forms an immortal sheath core structure under low-frequency long-period electromagnetic perturbations.
 [Results] The concomitant bright ring nature of a companionless black hole is clarified, the life paradox of the accretion disk is solved, and the joint stabilization mechanism of angular momentum-magnetic stiffness of the circulation is predicted.
 [Limited] The perturbation effect of interstellar medium collision on circulation and the saturation behavior of Z’s-emf at extreme accretion rate (M ̇>10−4M⊙/year) are not quantified.
 [Conclusion] Magnetized plasma circulation can be used as a lifelong companion for massive black holes, and its existence exceeds the evolutionary period of galaxies.
