Abstract:
Open clusters (OCs) are crucial for studying the formation and
evolution of the Galactic disc. However, the lack of a large number of
OCs analyzed homogeneously hampers the investigations about chemical
patterns and the existence of Galactocentric radial and vertical
gradients, or an age-metallicity relation. To overcome this, we have
designed the Open Cluster Chemical Abundances from Spanish
Observatories survey (OCCASO). We aim to provide homogeneous radial
velocities, physical parameters and individual chemical abundances of
six or more Red Clump stars for a sample of 25 old and
intermediate-age OCs visible from the Northern hemisphere. To do so,
we use high resolution spectroscopic facilities (R∼62,000) available
at Spanish observatories. We present the motivation, design and
current status of the survey, together with the first data release of
radial velocities for 77 stars in 12 OCs, which represents about 50%
of the survey. We include clusters never studied with high-resolution
spectroscopy before (NGC 1907, NGC 6991, NGC 7762), and clusters in
common with other large spectroscopic surveys like the Gaia-ESO Survey
(NGC 6705) and APOGEE (NGC 2682 and NGC 6819). We perform internal
comparisons between instruments to evaluate and correct internal
systematics of the results, and compare our radial velocities with
previous determinations in the literature, when available. Finally,
radial velocities for each cluster are used to perform a preliminar
kinematic study in relation with the Galactic disc.
Description:
We present results of radial velocities for stars in 12 completed
clusters (77 stars), and the reference stars Arcturus and µ Leo.
This is a total of 79 stars. We include radial velocities from
individual spectra, and final radial velocities from combined spectra
which reach a minimum signal-to-noise ratio of 70. Comparison with the
literature is included in the cases which the stars had previous
measurements.
