Abstract:
The DANCe survey provides photometric and astrometric (position and
proper motion) measurements for approximately 2 millions unique
sources in a region encompassing approximately 80deg2 centered
around the Pleiades cluster. We aim at deriving a complete census of
the Pleiades, and measure the mass and luminosity function of the
cluster. Using the probabilistic selection method described in Sarro
et al. (2014A&A...563A..45S 2014A&A...563A..45S, Cat. J/A+A/563/A45), we identify high
probability members in the DANCe (i>14mag) and Tycho-2 (V<12mag)
catalogues, and study the properties of the cluster over the
corresponding luminosity range. We find a total of 2109 high
probability members, of which 812 are new, making it the most
extensive and complete census of the cluster to date. The luminosity
and mass functions of the cluster are computed from the most massive
members down to 0.025M☉. The size, sensitivity and quality of
the sample result in the most precise luminosity and mass functions
observed to date for a cluster. Our census supersedes previous studies
of the Pleiades cluster populations, both in terms of sensitivity and
accuracy.
