Abstract

type:Article

We consider a collimation and acceleration mechanism for relativistic jets emanating from an inner region of a relativistic accretion disk surrounding a Kerr black hole, with Keplerian angular momentum under disk radiation fields, taking into account the effect of radiation drag. When the jets consist of electron-positron pair plasmas and the disk luminosity is of the order of the Eddington luminosity, we found that the terminal speed is about 0.9 c for a Schwarzschild case, while it becomes ～ 0.96c for an extreme Kerr case. In such a case, the opening angle of jets is of the order of 5°. We also examined the opening angle and the listing degree when the disk radiation is not axisymmetric, but has a one-armed pattern. For the case of 0.3 amplitude, the opening angle is of the order of a few degrees, and the jet direction is bent by several degrees to 10°.
