Search for Extremely Metal-poor Stars with Gemini-N/Graces. I. Chemical-abundance Analysis
The Astrophysical Journal, 2023 We present stellar parameters and abundances of 13 elements for 18 very metal-poor (VMP; [Fe/H] < –2.0) stars, selected as extremely metal-poor (EMP; [Fe/H] < –3.0) candidates from the Sloan Digital Sky Survey and Large sky Area Multi-Object Fiber ...

Dwarf galaxy populations in present-day galaxy clusters – I. Abundances and red fractions [PDF]
, 2011 We compare the galaxy population in the Virgo, Fornax, Coma and Perseus cluster to a state-of-the-art semi-analytic model, focusing on the regime of dwarf galaxies with luminosities from approximately 108 to 109 L⊙.

The Evolution of the Elemental Abundances in the Gas and Dust Phases of the Galaxy [PDF]
, 1997 We present models for the evolution of the elemental abundances in the gas and dust phases of the interstellar medium (ISM) of our Galaxy by generalizing standard models for its dynamical and chemical evolution.

The Stellar Abundances for Galactic Archaeology (SAGA) data base - II. Implications for mixing and nucleosynthesis in extremely metal-poor stars and chemical enrichment of the Galaxy [PDF]
, 2010 We discuss the characteristics of known extremely metal-poor (EMP) stars in the Galaxy using the Stellar Abundances for Galactic Archaeology (SAGA) database (Suda et al. 2008, PASJ, 60, 1159).

Abundance gradients in elliptical galaxies [PDF]
Astronomy & Astrophysics, 2003 Abundance gradients predicted by dissipative models of galaxy formation are studied with the aid of mass models of spherical galaxies obeying the Sersic R 1=n law in projection. The link between metallicity and stellar binding energies and angular momenta is derived from the "concentration model" by Lynden-Bell (1975) with the addition of a terminal ...

Chromium: NLTE abundances in metal-poor stars and nucleosynthesis in the Galaxy [PDF]
, 2010 Aims. We investigate statistical equilibrium of Cr in the atmospheres of late-type stars to ascertain whether the systematic abundance discrepancy between Cr I and Cr II lines, as often found in previous work, is due to deviations from local ...

The Origin of the Nuclear Star-forming Ring in NGC 3182
The Astronomical Journal, 2023 We investigate the stellar and ionized gas kinematics, and stellar populations of NGC 3182 galaxy using integral field spectrograph data from the Calar Alto Legacy Integral Field Area survey. We try to clarify the nature of the ring structure in NGC 3182.
