Brown Dwarfs in the Pleiades Cluster
We have discovered a relatively large number of brown dwarf candidates in the Pleiades young open cluster as a result of a deep CCD IZ survey covering 1 deg^2 down to limiting magnitudes I ~22 and Z ~21. Follow-up infrared photometry and low/intermediate-resolution spectroscopy of seven of our candidates in the interval 20 > I > 17.8 allow us to
