Exploring the Sun's birth radius and the distribution of planet building blocks in the Milky Way galaxy: A multi-zone Galactic chemical evolution approach
Junichi Baba, Takayuki R. Saitoh, Takuji Tsujimoto
We explore the influence of the Milky Way galaxy's chemical evolution on the formation, structure, and habitability of the Solar system. Using a multi-zone Galactic Chemical Evolut…
Impacts of the Local arm on the local circular velocity inferred from the Gaia DR3 young stars in the Milky Way
Aisha S. Almannaei, Daisuke Kawata, Junichi Baba +3
A simple one-dimensional axisymmetric disc model is applied to the kinematics of OB stars near the Sun obtained from Gaia DR3 catalogue. The model determines the 'local centrifugal…
Dynamical Influence of a Central Massive Object on Double-Barred Galaxies: Self-Destruction Mechanism of Secondary Bars
Naoki Nakatsuno, Junichi Baba
Double-barred galaxies exhibit sub-kpc secondary stellar bars that are crucial for channeling gases towards a central massive object (CMO) such as a supermassive black hole or a nu…
Efficient radial migration by giant molecular clouds in the first several hundred Myr after the stellar birth
Yusuke Fujimoto, Shu-ichiro Inutsuka, Junichi Baba
Stars in the Galactic disc, including the Solar system, have deviated from their birth orbits and have experienced radial mixing and vertical heating. By performing hydrodynamical…
Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution
Jin Koda, Akihiko Hirota, Fumi Egusa +23
We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…
Impact of bar resonances in the velocity-space distribution of the solar neighbourhood stars in a self-consistent -body Galactic disc simulation
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +3
The velocity-space distribution of the solar neighbourhood stars shows complex substructures. Most of the previous studies use static potentials to investigate their origins. Inste…
