Scientific paper

The predicament of a star moving through the intense radiation field of an active galactic nucleus (AGN) is considered. It is found that for stars which get sufficiently close to the source of the AGN continuum radiation - yet well outside the tidal radius of any associated massive body - enhanced mass loss occurs. Attention is given to irradiated photospheres, by demonstrating the possibility of the existence of highly turbulent motions in photospheres at modest incident flux levels. It is suggested that the feeding rates calculated for the tidal disruption/black hole models of AGN sources have previously been underestimated.
