The Metallicity Gradient of the Old Galactic Bulge Population

, 2014
Understanding the structure, formation and evolution of the Galactic Bulge requires the proper determination of spatial metallicity gradients in both the radial and vertical directions.

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

The Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution

Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies

The Astrophysical Journal
We performed N -body/smoothed particle hydrodynamics simulations of isolated spiral galaxies with various bulge-to-disk mass ratios ( M _bulge / M _disk ) from 0.02 to 0.2 to investigate mass transport from galactic scales (10 kpc) down to circumnuclear ...
