FRADO model of the Broad Line Region in Active Galactic Nuclei

Original language description

Broad Emission Lines are the most characteristic features of active galaxies but the mechanism of the line formation is still under debate. In 2011 we proposed that the Hβ lines are formed in a Failed Radiatively Accelerated Dusty Outflow (FRADO). In this paper we investigate this mechanism in more detail. We calculated the motion of dusty clouds taking into account the dust evaporation which arises when they are additionally illuminated by the central source. Our model explains the location and extension of the Broad Line Region as well as its large turbulent motion superimposed on Keplerian rotation. However, an enhancement of the dust opacity or additional mechanisms are necessary to push the material high enough above the disk.
