We have measured the strengths of Ca II Triplet and Mgb stellar absorption
lines in the nuclear and off-nuclear spectra of Seyfert galaxies. These
features are diluted to varying degrees by continuum emission from the active
nucleus and from young stars. Ca II Triplet strengths can be enhanced if
late-type supergiant stars dominate the near-IR light. Thus, objects with
strong Ca II Triplet and weak Mgb lines may be objects with strong bursts of
star formation. We find that for most of our sample the line strengths are at
least consistent with dilution of a normal galaxy spectrum by a power law
continuum, in accord with the standard model for AGN. However, for several
Seyferts in our sample, it appears that dilution by a power law continuum
cannot simultaneously explain strong Ca II Triplet and relatively weak Mgb.
Also, these objects occupy the region of the IRAS color-color diagram
characteristic of starburst galaxies. In these objects it appears that the
optical to near-IR emission is dominated by late-type supergiants produced in a
circumnuclear burst of star formation.Comment: 4 pages, 3 figures, to appear in Advances in Space Research,
