Stationary accelerators around Keplerian disks of aligned magnetized collapsed objects: Pair production and gamma-ray emission

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
