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…
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…
Early chemo-dynamical evolution of dwarf galaxies deduced from enrichment of r-process elements
Yutaka Hirai, Yuhri Ishimaru, Takayuki R. Saitoh +3
The abundance of elements synthesized by the rapid neutron-capture process (r-process elements) of extremely metal-poor (EMP) stars in the Local Group galaxies gives us clues to cl…
Gas and stellar spiral arms and their offsets in the grand-design spiral galaxy M51
Fumi Egusa, Erin Mentuch Cooper, Jin Koda +1
Theoretical studies on the response of interstellar gas to a gravitational potential disc with a quasi-stationary spiral arm pattern suggest that the gas experiences a sudden compr…
Eventful Evolution of Giant Molecular Clouds in Dynamically Evolving Spiral Arms
Junichi Baba, Kana Morokuma-Matsui, Takayuki R. Saitoh
The formation and evolution of giant molecular clouds (GMCs) in spiral galaxies have been investigated in the traditional framework of the combined quasi-stationary density wave an…
Radial distributions of arm-gas offsets as an observational test of spiral theories
Junichi Baba, Kana Morokuma-Matsui, Fumi Egusa
Theories of stellar spiral arms in disk galaxies can be grouped into two classes based on the longevity of a spiral arm. Although the quasi-stationary density wave theory supposes…
