Role of galactic gaseous halos in recycling enriched winds from bulges to disks: A new bulge-disk chemical connection
K. Bekki, T. Tsujimoto, M. Chiba
We demonstrate for the first time that gaseous halos of disk galaxies can play a vital role in recycling metal-rich gas ejected from the bulges and thus in promoting chemical evolu…
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…
Fossil Imprints of Outflow from the Galactic Bulge in Elemental Abundances of Metal-Rich Disk Stars
Takuji Tsujimoto
We explore the elemental abundance features of metal-rich disk stars, highlighting the comparisons made with those of the recently revealed Galactic bulge stars. A similarity betwe…
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…
First Detection of NaI D lines in High-Redshift Damped Lyman-alpha Systems
Sohei Kondo, Naoto Kobayashi, Yosuke Minowa +15
A Near-infrared (1.18-1.35 micron) high-resolution spectrum of the gravitationally-lensed QSO APM 08279+5255 was obtained with the IRCS mounted on the Subaru Telescope using the AO…
