First Stellar Abundances in NGC 6822 from VLT-UVES and Keck-HIRES Spectroscopy [PDF]
, 2000 We have obtained the first high-resolution spectra of individual stars in the dwarf irregular galaxy NGC 6822. The spectra of the two A-type supergiants were obtained at the Very Large Telescope and Keck Observatories, using the Ultraviolet-Visual ...

Lithium abundance evolution in open clusters: Hyades, NGC752, and M67
, 2013 Mixing mechanisms bring the Li from the base of the convective zone to deeper and warmer layers where it is destroyed. These mechanisms are investigated by comparing observations of Li abundances in stellar atmospheres to models of stellar evolution ...

About trend in zinc stellar abundances with metallisity
Odessa Astronomical Publications, 2007 We have carried out investigation of zinc abundance behavior in wide range of stellar metallicities from 0 to -5. It has been determined zinc abundance using our Zn atom model and NonLTE calculation method.

The Metal-Rich Universe: Formation and evolution of the Galactic bulge: constraints from stellar abundances [PDF]
, 2006 Aims. We compute the chemical evolution of the Galactic bulge in the context of an inside-out model for the formation of the Milky Way. The model contains updated stellar yields from massive stars.

New and updated stellar parameters for 90 transit hosts. The effect of the surface gravity
, 2013 Context. Precise stellar parameters are crucial in exoplanet research for correctly determining of the planetary parameters. For stars hosting a transiting planet, determining of the planetary mass and radius depends on the stellar mass and radius, which

NGC 1856: Using Machine Learning Techniques to Uncover Detailed Stellar Abundances from MUSE Data
The Astronomical JournalWe present the first application of the novel approach based on data-driven machine learning methods applied to Multi-Unit Spectroscopic Explorer (MUSE) field data to derive stellar abundances of star clusters.
