A pilot study on the CSST astrometric capability: Detecting astrometric binaries with Gaia synergy via simulated data
Shangyu Wen, Shilong Liao, Zhaoxiang Qi +8
Context. The China Space-station Survey Telescope (CSST) will provide deep, wide-field epoch astrometry during its 10-year mission. Astrometric binary orbits constrain the masses o…
Refining the Gaia DR3 Parallax Zero-point: A Hybrid Approach Combining Global Parametric Correction with Local Refinement
Ye Ding, Shilong Liao, Zhaoxiang Qi +3
The Gaia Data Release 3 (GDR3) parallaxes are affected by a complex bias that depends on stellar magnitude, color, and celestial position, with amplitudes reaching tens of microarc…
Constraining the inclination of binary system orbits with the astrometric excess noise from Gaia DR3
Shilong Liao, Ye Ding, Shangyu Wen +2
Orbital inclination is crucial in determining the binary mass. The astrometric excess noise contains the orbital motion information, which can be used to constrain the inclination.…
Analysis of Gaia Data Release 3 Parallax bias in the Galactic plane
Ye Ding, Shilong Liao, Qiqi Wu +2
The systematic errors are inevitable in Gaia published astrometric data. Lindegren et al. (L21) proposed a global recipe to correct for the GEDR3 parallax zero point offset, which…
Simulation of CSSTs astrometric capability
Zhensen Fu, Zhaoxiang Qi, Shilong Liao +5
The China Space Station Telescope (CSST) will enter a low Earth orbit around 2024 and operate for 10 years, with seven of those years devoted to surveying the area of the median-to…
