期刊全称 | Accuracy of Element Abundances from Stellar Atmospheres | 期刊简称 | Proceedings of Two S | 影响因子2023 | Rainer Wehrse | 视频video | | 学科分类 | Lecture Notes in Physics | 图书封面 |  | 影响因子 | To get a reasonably realistic picture of the structure and evolution of stars one needs to know accurately the abundances of chemical elements and their isotopes in the stellar atmosphere and in the galactic environment of the stars. The articles collected in this volume give a modern review of the abundance accuracies for main-sequence stars. After a general introduction in the first part the accuracies of atomic transition probabilities, ionization and excitation cross-sections, and line broad- ening data are discussed. In the second part the specific problems and results for different stellar types are presented, and, finally, an overview on the possibilities of abundance determinations for stars outside the Galaxy is given. | Pindex | Conference proceedings 1990 |
