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,…
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…
Comparison of bar formation mechanisms I: does a tidally-induced bar rotate slower than an internally-induced bar?
Yirui Zheng, Juntai Shen
Galactic bars can form via the internal bar instability or external tidal perturbations by other galaxies. We systematically compare the properties of bars formed through the two m…
Dynamical Origin of the Vertical Metallicity Gradient of the Milky Way Bulge
Bin-Hui Chen, Juntai Shen, Zhong Liu
A vertical metallicity gradient in the Milky Way bulge is well-established. Yet, its origin has not been fully understood under the Galactic secular evolution scenario. We construc…
