Supernova Nucleosynthesis and Extremely Metal-Poor Stars
Nozomu Tominaga, Hideyuki Umeda, Keiichi Maeda +2
We investigate hydrodynamical and nucleosynthetic properties of the jet-induced explosion of a population III star and compare the abundance patterns of the yields with…
The Dichotomy of the Halo of the Milky Way
Daniela Carollo, Timothy C. Beers
We summarize evidence that the halo of the Milky Way comprises two different, and broadly overlapping, stellar components. The two structures exhibit different chemical composition…
Nucleosynthesis in novae: experimental progress in the determination of nuclear reaction rates
Alain Coc
The sources of nuclear uncertainties in nova nucleosynthesis have been identified using hydrodynamical nova models. Experimental efforts have followed and significantly reduced tho…
Highly He-Rich Matter Dredged Up by Extra Mixing through Stellar Encounters in Globular Clusters
Takuma Suda, Takuji Tsujimoto, Toshikazu Shigeyama +1
The unveiled main-sequence splitting in omega Centauri as well as NGC 2808 suggests that matter highly-enriched in He (in terms of its mass fraction Y~0.4) was produced and made th…
The IMF of Extremely Metal-Poor Stars and the Probe into the Star-Formation Process of the Milky Way
Yutaka Komiya, Takuma Suda, Asao Habe +1
We discuss the star formation history of the Galaxy, based on the observations of extremely metal-poor stars (EMP) in the Galactic halo, to gain an insight into the evolution and s…
Surface pollution of main-sequence stars through encounters with AGB ejecta in omega Centauri
Takuji Tsujimoto, Toshikazu Shigeyama, Takuma Suda
The origin of a double main-sequence (MS) in omega Centauri is explored. We have shown from theoretical calculations on the stellar evolution that the colors of MS stars are shifte…
