New Members of the Cluster Family in Nearby Lenticulars
  Using spectra obtained with the Keck I telescope we have demonstrated conclusively that the faint (23<V<24 mag.) and unusually extended objects we discovered in HST images of the lenticular galaxies, NGC 1023 and NGC 3384, are star clusters associated with their respective galaxies. In the case of NGC 1023 we were further able to establish that these objects are old (>7--8 Gyr), moderately metal-rich ([Fe/H]=-0.58+/-0.24) and, having a system rotation curve which is very similar to that of the host galaxy, are associated with the lenticular disk. Alpha-element to iron abundance ratios are highly supersolar with [alpha/Fe] between +0.3 and +0.6. With moderately high metallicities and luminosities, and effective radii in the range 7--15 pc (compared to the 2--3 pc sizes typical of normal globular and open clusters), this population of clusters has no known analog in the Milky Way or elsewhere in the Local Group.
