A six-square-degree survey for Pleiades low-mass stars and brown dwarfs

We present the results of a six-square-degree Pleiades survey in I and Z, which is photometrically complete to approximately IKP=19.2 (ICou=19.6 in the Pleiades). We remove non-cluster contamination on the basis of proper motions and infrared photometry, and present 339 candidate cluster members, 30...

Zusammenfassung:We present the results of a six-square-degree Pleiades survey in I and Z, which is photometrically complete to approximately IKP=19.2 (ICou=19.6 in the Pleiades). We remove non-cluster contamination on the basis of proper motions and infrared photometry, and present 339 candidate cluster members, 30 of which are fainter than IKP=17.5, and are thus strong brown-dwarf candidates.
