Abstract

We discuss photometric and spectroscopic data of the E/S0 galaxy NGC 4342, obtained with the Hubble Space Telescope (HST). This galaxy harbors, in addition to its outer disk, a very small, stellar disk in its nucleus. Jeans-modeling suggests the presence of a 3-6 $\times 10^8 \Msun$ black hole (BH) in the nucleus. This galaxy therefore deviates significantly from the correlation between BH mass and bulge mass, found for other BH candidate galaxies.
