Abstract (from CDS):

We have carried out a brown dwarf search over an area of 14x23arcmin2 near the central portion of the Pleiades open cluster in five optical and near-infrared bands (i ', Z, J, H, Ks) with 10σ detection limits of i '∼ 22.0, J ∼ 20.0 and Ks ∼ 18.5 mag. The surveyed area has large extinction in excess of AV= 3 in the Pleiades region. We detected four new brown dwarf candidates from the colour-colour (J -K, i '-J) and the colour-magnitude (J, i '-K) diagrams. We estimated their masses as 0.046 M☉down to 0.028 M☉. The least massive one is estimated to have a mass smaller than Roque25 or int-pl-IZ-69, and possibly the lowest-mass object found so far in the Pleiades cluster.
