On photons and matter inversion spheres from complex super-spinars accretion structures

Abstract Our analysis focus on the dragging effects accretion flows and jet emission in Kerr super-spinars. These attractors are characterized by peculiar structures as double tori, or special dragged tori ergoregion, produced balance of hydrodynamic centrifugal forces also super-spinars repulsive gravity. We investigate flows, constituted particles photons, from toroids orbiting a central super-spinar. As results our analysis, both properties characterizing these geometries, that constitute possible strong observational signatures attractors, highlighted. found flow is closed surfaces, defining inversion coronas (spherical shell), with null toroidal velocity ( $$u^{\phi }=0$$ u ? = 0 ) embedding singularity. proved this region distinguishes proto-jets driven co-rotating counter-rotating flows. Therefore cases carries information about around attractor, demonstrating points can an aspect capable distinguishing
