Evaluation of the ICRF stability from position time series analysis
Niu Liu, Sebastien Lambert, Felicitas Arias +2
The celestial reference frame is realized by absolute positions of extragalactic sources that are assumed to be fixed in the space. The fixing of the axes is one of the crucial poi…

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…
