摘要：
我们的分析重点研究Kerr超自旋星对吸积流和喷流发射的拖曳效应。这些引力体具有独特的吸积结构，如双环面或能层中的特殊拖曳环面，由流体动力学与离心力的平衡以及超自旋星排斥引力效应产生。我们研究了由粒子和光子组成的吸积流，这些流来自环绕中心Kerr超自旋星的环面。作为分析结果，我们强调了在吸积流和喷流中表征这些几何形状的特性，这些特性构成了这些引力体可能的强观测特征。我们发现，该流以闭合表面为特征，定义了反转冕（球壳），其中粒子流的环向速度为零（$u^ϕ=0$），包裹着中心奇点。我们证明，该区域区分了原喷流和吸积驱动流，以及同向旋转和反向旋转流。因此，在这两种情况下，流都携带着有关中心引力体周围吸积结构的信息，表明反转点可以构成一种能够区分超自旋星的观测特征。
英文摘要：
Our analysis focus on the dragging effects on the accretion flows and jet emission in Kerr super-spinars. These attractors are characterized by peculiar accretion structures as double tori, or special dragged tori in the ergoregion, produced by the balance of the hydrodynamic and centrifugal forces and also effects of super-spinars repulsive gravity. We investigate the accretion flows, constituted by particles and photons, from toroids orbiting a central Kerr super-spinar. As results of our analysis, in both accretion and jet flows, properties characterizing these geometries, that constitute possible strong observational signatures or these attractors, are highlighted. We found that the flow is characterized by closed surfaces, defining inversion coronas (spherical shell), with null the particles flow toroidal velocity ($u^ϕ=0$) embedding the central singularity. We proved that this region distinguishes proto-jets and accretion driven flows, co-rotating and counter-rotating flows. Therefore in both cases the flow carries information about the accretion structures around the central attractor, demonstrating that inversion points can constitute an observational aspect capable of distinguishing the super-spinars.
