CNO in Giant Metal-Poor Stars
Abstract
We present the chemical abundance analysis for elements carbon, nitrogen, oxygen and the carbon isotopic ratio in a sample of metal-poor stars selected from the RAVE survey based on their extreme radial velocities. Stellar parameters were derived using Gaia photometry and parallaxes, and elemental abundances were determined from high-resolution UVES spectra obtained at the ESO Very Large Telescope. The stars span a wide metallicity range (-2.9 ___ [Fe/H] ___ -1.2) and, for the majority of the sample, exhibit kinematic properties consistent with the Galactic outer halo population.
