Dynamics of line-driven disk winds in Active Galactic Nuclei

Abstract

We present the results of time-dependent hydrodynamic calculations of line- driven winds from accretion disks in AGN. To calculate the radiation force, we take into account radiation from the disk and the central engine. The gas temperature and ionization state in the wind are calculated self-consistently. We find that a disk accreting onto a 10^8 MSUN black hole at the rate of 1.8 MSUN/YR can launch a wind at about 10^16 cm from the central engine. The X-rays from the central object are attenuated by the disk atmosphere so they cannot prevent the local disk radiation from pushing matter away from the disk. For a reasonable X-ray opacity, the disk wind can be accelerated by the central UV radiation to velocities of up to 15000 km/s at a distance of about 10^17 cm from the central engine. The covering factor of the disk wind is $\sim 0.2$. The wind is unsteady and consists of an opaque, slow vertical flow near the disk that is bounded on the polar side by a high-velocity stream. A typical column density through the fast stream is a few 10^23 cm^-2. The fast stream contributes nearly 100% to the total wind mass loss rate of 0.5 MSUN/YR.
