Old Open Clusters as Tracers of Galactic Chemical Evolution: the BOCCE Projectmass stars and as tracers of the Galactic disk properties. Since old OCs allow us to probe the lifetime of the Milky Way disk, up to about 10 Gyr ago, they can be used to study the disk evolution withtime, and in particular its chemical history.作者: sundowning 時間: 2025-3-22 02:41
Chemical Abundances and Mixing in Red Clump Stars of the Galaxyand abundances of .C, .C, N, O and other mixing sensitive chemical elements were investigated. Elemental ratios in the sample of field stars are compared to the results available for evolved stars in open clusters and to the theoretical prediction of extra mixing in stellar interiors.作者: TEN 時間: 2025-3-22 06:44

Observational Constraints on Nucleosynthesis in AGB Starsspite the uncertainties still existing in the chemical analysis of these stars, the determination of the abundances of several key species in their atmospheres (lithium, s-elements, carbon and magnesium isotopic ratios etc.) is an useful tool to test these theories and the mixing processes during th作者: comely 時間: 2025-3-22 19:17 作者: 蒼白 時間: 2025-3-22 21:13
A Comparison of Methods for Photospheric Abundance Determinations in K-Type Starsiques and compared the results obtained in order to establish their respective merits and faults. The two spectroscopic methods give consistent results suggesting that non- LTE effects are small, whereas the ‘mixed’ spectroscopic-photometric method leads to photospheric parameters and abundances sys作者: 禍害隱伏 時間: 2025-3-23 04:40 作者: 下邊深陷 時間: 2025-3-23 06:11
