Abstract:
Ruprecht 147 is the oldest (2.5Gyr) open cluster in the solar
vicinity (<300pc), making it an important target for stellar
evolution studies and exoplanet searches.
We aim to derive a census of members and the luminosity, mass, and
spatial distributions of the cluster.
We used an astro-photometric data set including all available
information from the literature together with our own observations. We
processed the data with an updated version of an existent membership
selection methodology.
We identify 259 high-probability candidate members, including 58
previously unreported. All these candidates cover the luminosity
interval between G>6mag to i<21mag. The cluster luminosity and
mass distributions are derived with an unprecedented level of details
allowing us to recognize, among other features, the Wielen dip. The
mass distribution in the low-mass regime drops sharply at 0.4M☉
even though our data are sensitive to stellar masses down to
0.1M☉, suggesting that most very-low-mass members left the
cluster as the result of its dynamical evolution. In addition, the
cluster is highly elongated (ellipticity∼0.5) towards the galactic
plane, and mass segregated.
Our combined Gaia+DANCe data set allows us to obtain an extended list
of cluster candidate members, and to derive luminosity, mass, and
projected spatial distributions in the oldest open cluster of the
solar vicinity.
Description:
Tables 6 to 8 contain the catalogue of sources in a region of 6°
radius around the cluster centre.
Table 9 contains the sources classified as cluster members, their
diverse id, astrometry, photometry and cluster membership probability.
Tables 10 and 11 contain the cluster empirical sequence in the Gaia
and DANCe photometry, respectively.
Finally, Table 12 contains the mass distribution from the Gaia DR2
catalogue using the COLIBRI isochrone.
