| Research Abstract |
The purpose of the present research project is to promote the basic studies on red giant stars and collaborations among several groups working on this subject. To promote tha basic studies, major part of the fund has been used for supporting travels to go to observations in major domestic observatories including Okayamas Astrophysical Observatory, Kiso Schmidt Station, Nobeyama Radio Observatory and so on. To promote collaborations among several groups working on observational, experimental and theoretical works, the fund is used to support workshops and symposia.
To summarize and evaluate our researches during 3 years under this project, a final symposium on red giant stars is done to clarify the following subjects: 1. Atmospheric structure and chemical composition. 2. Chromospheres and outer envelopes. 3. Red giants in the Galaxy and galaxies. 4. Dust formation in the circumstellar envelopes of red giants. 5. Molecular formation in the circumstellar envelopes of red giants. 6. Internal evolution and mass-loss.
The details of this symposium will be reported in the final reprt of our project by the end of the fiscal year 1987.
