Kinematics of Solar neighborhood stars and its dependency on age and metallicity
Zong-Bo Huyan, Zi Zhu, Jia-Cheng Liu
We have constructed a catalog containing best available astrometric, photometric, radial velocity and astrophysical data for mainly F-type and G-type stars (called the Astrometric…
Aberration in proper motions for stars in our Galaxy
Jia-Cheng Liu, Yi Xie, Zi Zhu
Accelerations of both the solar system barycenter (SSB) and stars in the Milky Way cause a systematic observational effect on the stellar proper motions, which was first studied in…
Constructing a Galactic coordinate system based on near-infrared and radio catalogs
Jia-Cheng Liu, Zi Zhu, Bo Hu
The definition of the Galactic coordinate system was announced by the IAU Sub-Commission 33b on behalf of the IAU in 1958. For more than 50 years the definition of the Galactic coo…
Reconsidering the galactic coordinate system
Jia-Cheng Liu, Zi Zhu, Hong Zhang
Initially defined by the IAU in 1958, the galactic coordinate system was thereafter in 1984 transformed from the B1950.0 FK4-based system to the J2000.0 FK5-based system. In 1994,…
