Project summary

The aim of the project is the investigation of fundamental problems concerning origin of chemical elements in the Universe and evolution of chemical composition of stars, galaxies and clusters of galaxies.

Following problems will be considered in the project:


- Compilation and analysis of most complete data on astrophysical important nuclear reactions;
- Derivation of yields of heavy elements in the processes of nuclesynthesis occurring at different stages of stellar evolution, including red giant phases, and novae and supernovae explosions, on the basis of recent theoretical and observational data;
- Development of models with mass exchange between stars and interstellar medium, and between galaxies and intergalactic medium;
- Construction of a general model of star formation in galaxies and chemical evolution of galaxies and their clusters.

As a result of this study a general picture of the process of formation and evolution of stars and galaxies and of evolution of chemical composition of the matter in the Universe should be obtained. This study will be based on current understanding of physics and evolution of stars and galaxies, as well as on theoretical and experimental nuclear data.

The project supposes wide international cooperation of experts on nuclear physics and astrophysics.
