Abstract:
The Measuring at Intermediate Metallicity Neutron-Capture Elements
(MINCE) project aims to provide high-quality neutron-capture
abundances measurements for several hundred stars at an intermediate
metallicity of -2.5<[Fe/H]←1.5. This project will shed light on the
origin of the neutron-capture elements and the chemical enrichment of
the Milky Way. Aims. The goal of this work is to chemically
characterize the second sample of the MINCE project and compare the
abundances with the galactic chemical evolution model at our disposal.
We performed a standard abundance analysis based on one-dimensional
(1D) local thermodynamic equilibrium (LTE) model atmospheres based on
high-resolution and high-signal-to-noise-ratio (S/N) spectra from
Ultraviolet and Visual Echelle Spectrograph (UVES).
We provide the kinematic classification (i.e., thin disk, thick disk,
thin-to-thick disk, halo, Gaia Sausage Enceladus, Sequoia) of 99 stars
and the atmospheric parameters for almost all stars. We derived the
abundances for light elements (from Na to Zn) and neutron-capture
elements (Rb, Sr, Y, Zr, Ba, La, Ce, Pr, Nd, Sm, and Eu) for a
subsample of 32 stars in the metallicity range of -2.5<[Fe/H]←1.00.
In the subsample of 32 stars, we identified eight active stars
exhibiting (inverse) P-Cygni profile and one Li-rich star,
CD 28-11039. We find a general agreement between the chemical
abundances and the stochastic model computed for the chemical
evolution of the Milky Way halo for elements Mg, Ca, Si, Ti, Sc, Mn,
Co, Ni, Zn, Rb, Sr, Y, Zr, Ba, La, and Eu .
The MINCE project has already significantly increased the number of
neutron-capture elements measurements in the intermediate metallicity
range. The results from this sample are in perfect agreement with the
previous MINCE sample. The good agreement between the chemical
abundances and the chemical evolution model of the Galaxy supports the
nucleosynthetic processes adopted to describe the origin of the
n-capture elements.
Description:
In this paper, we present a sample of 99 stars observed with
UVES@ESO-VLT/UT2, Paranal Observatory (Chile). The data were collected
between September 2020 and August 2021.
The MINCE project investigates the nucleosynthetic processes
that lead to the chemical elements production in the intermediate
metallicity range, -2.5<[Fe/H]←1.5, with a particular focus on the
bulk of elements heavier than iron (Z>30). In this work, we presented
the analysis carried out of high resolution and high signal-to-noise
UVES data of 94 stars. Of these we provide a detailed chemical
inventory for 32 stars, while for the remaining stars we only provide
[Fe/H] and atmospheric parameters.
All 99 stars observed were kinematically characterized and
divided into thin disk (42), thick disk (22), thin-to-thick disk (1)
and halo (34), where 6 and 3 halo stars belong to GSE and Sequoia,
respectively. Among the subsample of 32 stars with detailed chemical
analysis, 23 stars belong to the Galactic halo 9 to the thick-disk, 4
to GES and 2 to Sequoia.
