The Gaia–ESO Survey: Carbon Abundance in the Galactic Thin and Thick Disks
(The American Astronomical Society, 2020)
This paper focuses on carbon, which is one of the most abundant elements in the universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution. The origin of carbon and the relative ...
Metallicity and alpha-element abundance gradients along the Sagittarius Stream as seen by APOGEE
(IOP, 2020)
Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Observatory Galactic Evolution Experiment ...
A double stellar generation in the globular cluster NGC 6656 (M 22). Two stellar groups with different iron and s-process element abundances
(2009)
We present a chemical abundance analysis based on high resolution UVES spectra of seventeen bright giant stars in the Globular Cluster (GC) M 22. We obtained an average iron abundance of [Fe/H] = -1.76±0.02 (internal errors ...

Abundance analysis of planet-hosting and debris-disk stars
(Publishing house "Pero", 2014)
Beryllium abundances along the evolutionary sequence of the open cluster IC 4651-A new test for hydrodynamical stellar models
(EDP SCIENCES S A, 2010)
Context. Previous analyses of lithium abundances in main sequence and red giant stars have revealed the action of mixing mechanisms other than convection in stellar interiors. Beryllium abundances in stars with Li abundance ...
An analysis of the composite stellar population in M32
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We obtained long-slit spectra of high signal-to-noise ratio of the galaxy M32 with the Gemini Multi-Object Spectrograph at the Gemini-North telescope. We analysed the integrated spectra by means of full spectral fitting ...
