Precision Chemical Abundance Measurements [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractThis talk covers preliminary work in which we apply a strictly differential line-by-line chemical abundance analysis to high quality UVES spectra of the globular cluster NGC 6752. We achieve extremely high precision in the measurement of relative abundance ratios.

Elemental Abundances Of Solar Sibling Candidates [PDF]

, 2014
Dynamical information along with survey data on metallicity and in some cases age have been used recently by some authors to search for candidates of stars that were born in the cluster where the Sun formed.

Li-rich Giants Identified from LAMOST DR8 Low-resolution Survey

The Astronomical Journal, 2023
A small fraction of giants possess photospheric lithium (Li) abundance higher than the value predicted by the standard stellar evolution models, and the detailed mechanisms of Li enhancement are complicated and lack a definite conclusion.

Chemical abundances of LINER galaxies – nitrogen abundance estimations

Monthly Notices of the Royal Astronomical Society
ABSTRACT In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscopic data (3600 – 10 000 Å) of 40 LINERs from the Mapping Nearby Galaxies (MaNGAs) survey were considered.
