Galactic Bar Resonances Inferred from Kinematically Hot Stars in Gaia EDR3
Daisuke Kawata, Junichi Baba, Jason A. S. Hunt +5
Using a numerical simulation of an isolated barred disc galaxy, we first demonstrate that the resonances of the inner bar structure induce more prominent features in the action spa…
Remarkable migration of the solar system from the innermost Galactic disk; a wander, a wobble, and a climate catastrophe on the Earth
Takuji Tsujimoto, Junichi Baba
Recent knowledge of Galactic dynamics suggests that stars radially move on the disk when they encounter transient spiral arms that are naturally generated during the process of dis…
How do different spiral arm models impact the ISM and GMC population?
Alex R. Pettitt, Clare L. Dobbs, Junichi Baba +4
The nature of galactic spiral arms in disc galaxies remains elusive. Regardless of the spiral model, arms are expected to play a role in sculpting the star-forming interstellar med…
