Abstract
Recent studies have found a deficit of substellar objects in the Taurus cloud (Briceño et al. 1998; Luhman 2000). If confirmed, the higher low-mass cutoff in Taurus could have strong implications on IMF and substellar formation models. However, these previous studies have sampled the highest density regions of the Taurus cloud, and if brown dwarfs are ejected during their formation (Reipurth & Clarke 2001), a significant fraction of the substellar content of the cloud may have been missed. In order to enlarge the Taurus study, we have performed an optical (I,z) large photometric survey using the CFH12K camera on the Canada-France-Hawaii Telescope (CFHT). In this poster, we present new substellar candidates obtained from our (I,z) survey and further FORS1/VLT and LRIS/Keck spectroscopic analysis. We then compare our results with previous studies of Briceño et al. (2002) and Luhman et al. (2003).
