ZYJHK photometry in Upper Sco

DOI

We present first results from a deep (J=18.7), wide-field (6.5deg^2^) infrared (ZY JHK) survey in the Upper Sco association conducted within the science verification phase of the United Kingdom Infrared Telescope Infrared Deep Sky Survey Galactic Cluster Survey (GCS). Cluster members define a sequence well separated from field stars in the (Z-J, Z) colour-magnitude diagram. We have selected a total of 164 candidates with J =10.5-8.7mag from the (Z-J, Z) and (Y-J, Y) diagrams. We further investigated the location of those candidates in the other colour-magnitude and colour-colour diagrams to weed out contaminants. The cross-correlation of the GCS catalogue with the Two-Micron All-Sky Survey data base confirms the membership of 116 photometric candidates down to 20 Jupiter masses as they lie within a 2 circle centred on the association mean motion. The final list of cluster members contains 129 sources with masses between 0.3 and 0.007M_{sun}_.
