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 ...
