磁层被描述为一个系统组成的旋转塌陷星星连接由一个对齐的磁偶极子场到周围的理想化的同轴，非粘性冷开普勒磁盘。当导电盘的内部比星星旋转得更快时，磁层被电荷分离。磁层的一部分将与星星或与它被磁场连接的那部分圆盘共转。分离这种不同旋转区域的是没有等离子体的“间隙”。TeV γ射线光度的模型结果与某些双星中具有加速盘的坍缩星的观测结果进行了比较
The magnetosphere is described for a system consisting of a spinning collapsed star connected by an aligned magnetic dipole field to a surrounding idealized coaxial, nonviscous cool Keplerian disk. When the inner part of the conducting disk rotates more rapidly than the star, the magnetosphere is charge-separated. A part of the magnetosphere will corotate either with the star or with that part of the disk to which it is linked by the magnetic field. Separating such differently rotating regions are «gaps» empty of plasma. The model results for TeV γ-ray luminosity are compared with reported observations form certain collapsed stars with accelleration disks in binaries
