The one of the possibilities concerning the cause of AGN jets is the super-Eddington luminocity around the Massive Black Hole. If the case of optically thick state is assumed, we can define the super-Eddington temperature in the optically thick case, from the following condition that where r∗ = 2c2r/GM. The creation of electron- positron pairs and the pahse change are expected to occur in the such temperature rage around 109K, where the radiation pressure is dominant in the lower temperature and the pair pressure be in the higher one.
