Abstract The presence of a dense star cluster around the central black hole in AGNs can affect both the dynamics and the emission of the global system. We analyze the interaction of expanding stellar atmospheres with a nuclear wind outflowing from the central region of a Seyfert-like AGN nucleus. The envelopes can be confined by the bow shock arising from the interaction with the AGN nuclear wind. A non-negligible amount of matter is fed into this nuclear wind as a result of stellar mass loss and possible star collisions; at the same time, the envelopes surrounding the stars, produced by the stellar mass loss, turn out to be suitable for reproducing the observed Broad Line Region emission.

Abstract
Abstract The presence of a dense star cluster around the central black hole in AGNs can affect both the dynamics and the emission of the global system. We analyze the interaction of expanding stellar atmospheres with a nuclear wind outflowing from the central region of a Seyfert-like AGN nucleus. The envelopes can be confined by the bow shock arising from the interaction with the AGN nuclear wind. A non-negligible amount of matter is fed into this nuclear wind as a result of stellar mass loss and possible star collisions; at the same time, the envelopes surrounding the stars, produced by the stellar mass loss, turn out to be suitable for reproducing the observed Broad Line Region emission.
