SIRIUS Project. V. Formation of off-center ionized bubbles associated with Orion Nebula Cluster
Michiko S. Fujii, Kohei Hattori, Long Wang +4
Massive stars born in star clusters terminate star cluster formation by ionizing the surrounding gas. This process is considered to be prevalent in young star clusters containing m…
SIRIUS Project. IV. The formation history of the Orion Nebula Cluster driven by clump mergers
Michiko S. Fujii, Long Wang, Yutaka Hirai +3
The Orion Nebula Cluster (ONC) is an excellent example for understanding the formation of star clusters. Recent studies have shown that ONC has three distinct age populations and a…
Metallicity dependence of the Hercules stream in Gaia/RAVE data -- explanation by non-closed orbits
Kohei Hattori, Naoteru Gouda, Taihei Yano +4
The origin of the Hercules stream, the most prominent velocity substructure in the Solar neighbour disc stars, is still under debate. Recent accurate measurements of position, velo…
Imprints of Zero-Age Velocity Dispersions and Dynamical Heating on the Age-Velocity dispersion Relation
Jun Kumamoto, Junichi Baba, Takayuki R. Saitoh
Observations of stars in the the solar vicinity show a clear tendency for old stars to have larger velocity dispersions. This relation is called the age-velocity dispersion relatio…
Global Spiral Arms Formation by Non-linear Interaction of Wakelets
Jun Kumamoto, Masafumi Noguchi
The formation and evolution of galactic spiral arms is not yet clearly understood despite many analytic and numerical work. Recently, a new idea has been proposed that local densit…
