Abstract:
Open clusters are ideal laboratories to investigate a variety of
astrophysical topics, from the properties of the Galactic disk to
stellar evolutionary models. Knowing their metallicity and possibly
detailed chemical abundances is therefore important. However, the
number of systems with chemical abundances determined from high
resolution spectroscopy is still small.
To increase the number of open clusters with radial velocities and
chemical abundances determined from high resolution spectroscopy we
used publicly available catalogues of surveys in combination with Gaia
data.
Open cluster stars have been identified in the APOGEE and GALAH
spectroscopic surveys by cross-matching their latest data releases
with stars for which high-probability astrometric membership has been
derived in many clusters on the basis of the Gaia second data release.
Radial velocities have been determined for 131 and 14 clusters from
APOGEE and GALAH data, respectively. This is the first radial velocity
determination from high resolution spectra for 16 systems. Iron
abundances have been obtained for 90 and 14 systems from APOGEE and
GALAH samples, respectively. To our knowledge 66 of these clusters (57
in APOGEE and 9 in GALAH) do not have previous determinations in the
literature. For 90 and 7 clusters in the APOGEE and GALAH samples,
respectively, we have also determined average abundances for Na, Mg,
Al, Si, Ca, Cr, Mn, and Ni.
Description:
Radial velocities, Fe, Na, Mg, Al, Si, Ca, Cr, Mn, and Ni determined
from OCs candidates obtained from Gaia DR2 using the APOGEE DR14 and
GALAH DR2 samples.
