Abstract:
The study of open-cluster chemical abundances provides insights on
stellar nucleosynthesis processes and on Galactic chemo-dynamical
evolution. In this paper we present an extended abundance analysis of
10 species (Fe, Ni, Cr, V, Sc, Si, Ca, Ti, Mg, O) for red giant stars
in 18 OCCASO clusters. This represents a homogeneous sample regarding
the instrument features, method, line list and solar abundances from
confirmed member stars. We perform an extensive comparison with
previous results in the literature, and in particular with the Gaia
FGK Benchmark stars Arcturus and mu Leo. We investigate the
dependence of [X/Fe] with metallicity, Galactocentric radius
(6.5kpc<RGC<11kpc), age (0.3Gyr<Age<10Gyr), and height above the plane
(|z|<1000pc). We discuss the observational results in the
chemo-dynamical framework, and the radial migration impact when
comparing with chemical evolution models. We also use APOGEE DR14 data
to investigate the differences between the abundance trends in RGC and
|z| obtained for clusters and for field stars.
Description:
The Open Clusters Chemical Abundances from Spanish Observatories
survey (OCCASO) observations are performed with the high-resolution
echelle spectrographs available at Spanish observatories: CAFE at the
2.2 m telescope in the Centro Astronomico Hispano en Andalucia (CAHA),
FIES at the 2.5m NOT telescope in the Observatorio del Roque de los
Muchachos (ORM) and HERMES at the 1.2m Mercator telescope also in the
ORM. These instruments have similar resolution R>65000 and wavelength
range coverage 4000≤λ≤9000Å.
The typical obtained S/N is around 70 per pixel. In this catalogue, it
is included data from 81 nights of observations between January 2013 -
August 2016.
Individual abundances (Fe, Ni, Cr, V, Sc, Si, Ca, Ti, Mg, O) of 133
spectra from 117 stars in 18 open clusters weew obtained. The cluster
membership was re-analysed and average abundance values and
dispersions of abundance per cluster were obtained. The linelist used
for elements different of Fe s alos indicqted (see Casamiquela et al.,
2017MNRAS.470.4363C 2017MNRAS.470.4363C for the Fe linelist).
