Solar System Migration Points to a Renewed Concept: Galactic Habitable Orbits
Junichi Baba, Takuji Tsujimoto, Takayuki R. Saitoh
Astrophysical evidence suggests that the Sun was born near 5 kpc from the Galactic center, within the corotation radius of the Galactic bar, around 6-7 kpc. This presents challenge…
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…
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…
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…
Detecting a disk bending wave in a barred-spiral galaxy at redshift 4.4
Takafumi Tsukui, Emily Wisnioski, Joss Bland-Hawthorn +4
The recent discovery of barred spiral galaxies in the early universe () poses questions of how these structures form and how they influence galaxy evolution in the early unive…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
