Observed ﹩{{R}_{C}}-{{I}_{C}}﹩, I_C color–magnitude diagram of NGC 7129 constructed from the Keck LRIS photometry, uncorrected for reddening. Photometric errors are shown for all sources. The Siess et al. (2000) isochrones for 2 Myr, the approximate cluster age, and 100 Myr and the evolutionary track for a 0.1 M﹩_{\odot }﹩ star are overplotted. The shaded region represents the area where very low mass cluster members are expected to lie, including brown dwarf candidates. The Baraffe et al. (1998) models predict that the sub-stellar mass limit lies near I_C = 19.83 mag, where a handful of sources are evident in the cluster sequence. Deeper photometric surveys as well as spectroscopy are needed for confirmation.
