要旨
We investigated the correlation between nuclear/circumnuclear starbursts around active galactic nuclei (AGNs) and the AGN activities for 43 Seyfert galaxies in the CfA and 12 \ensuremathμm samples. We found that the circumnuclear starburst luminosity, as well as the nuclear starburst luminosity, is positively correlated with the AGN luminosity. Moreover, the nuclear starburst luminosity is more strongly correlated with the AGN luminosity normalized with the AGN Eddington luminosity than is the circumnuclear starburst luminosity. This implies that starbursts nearer the AGN could have a greater effect on AGN mass accretion. We also discuss these results from the viewpoint of the radiation effects from starbursts and sequential starbursts.
