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 ...

SP_Ace: a new code to derive stellar parameters and elemental abundances [PDF]
, 2015 Aims: We developed a new method of estimating the stellar parameters Teff, log g, [M/H], and elemental abundances. This method was implemented in a new code, SP_Ace (Stellar Parameters And Chemical abundances Estimator).

The Stellar Abundances for Galactic Archaeology (SAGA) Database – III. Analysis of enrichment histories for elements and two modes of star formation during the early evolution of the Milky Way [PDF]
, 2013 We study the enrichment histories for nine elements, C, four alpha-elements of Mg, Si, Ca, and Ti, Sc, and three iron-peak elements of Co, Ni, and Zn, by using a large number of stellar data, collected by the Stellar Abundances for Galactic Archaeology ...

How accretion of planet-forming disks influences stellar abundances [PDF]
Astronomy & Astrophysics, 2023 Millimeter sized dust grains experience radial velocities exceeding the gas velocities by orders of magnitude. The viscous evolution of the accretion disk adds disk material onto the central star's convective envelope, influencing its elemental ...

Residual Abundances in GALAH DR3: Implications for Nucleosynthesis and Identification of Unique Stellar Populations [PDF]
Astrophysical Journal, 2021 We investigate the [X/Mg] abundances of 16 elements for 82,910 Galactic disk stars from GALAH+ DR3. We fit the median trends of low-Ia and high-Ia populations with a two-process model, which describes stellar abundances in terms of a prompt core-collapse

The Astrophysical Journal, 2023 Stellar streams in the Galactic halo are useful probes of the assembly of galaxies like the Milky Way. Many tidal stellar streams that have been found in recent years are accompanied by a known progenitor globular cluster or dwarf galaxy.
