Kinematics of classical Cepheids in the Nuclear Stellar Disk
N. Matsunaga, K. Fukue, R. Yamamoto +13
Classical Cepheids are useful tracers of the Galactic young stellar population because their distances and ages can be determined from their period-luminosity and period-age relati…
Destruction of star clusters due to the radial migration in spiral galaxies
M. S. Fujii, J. Baba
Most stars in galactic disks are believed to be born as a member of star clusters or associations. Star clusters formed in disks are disrupted due to the tidal stripping and the ev…
Metallicities of Classical Cepheids in the Inner Galactic Disk
N. Matsunaga, D. Taniguchi, S. S. Elgueta +14
Metallicity gradients refer to the sloped radial profile of metallicities of gas and stars and are commonly seen in disk galaxies. A well-defined metallicity gradient of the Galact…
The dynamics of spiral arms in pure stellar disks
M. S. Fujii, J. Baba, T. R. Saitoh +3
It has been believed that spirals in pure stellar disks, especially the ones spontaneously formed, decay in several galactic rotations due to the increase of stellar velocity dispe…
