The Dependency of Bar Formation Timescale on Disk Mass Fraction, Toomre , and Scale Height
Bin-Hui Chen, Juntai Shen
Bars are one of the most prominent galactic structures. The classical swing-amplification theory can qualitatively describe the spontaneous bar instability of stellar disks. Still,…

Revisiting the Radial Metallicity Gradient-Age Relation in the Milky Way's Thin and Thick Disks
Ao Chen, Juntai Shen, Chun Wang +1
Galactic disks typically exhibit a negative radial metallicity gradient, indicating faster enrichment in the inner regions. Recent studies report that this gradient becomes flatter…

Comparison of Bar Formation Mechanisms. II. Does a Tidally Induced Bar Grow Faster Than an Internally Developed Bar?
Yirui Zheng, Juntai Shen, Xufen Wu +1
Bar structures can form internally due to the instability of their host galaxies or externally due to perturbations from other galaxies. We systematically quantify the growth times…
