Closeby Habitable Exoplanet Survey (CHES). II. An Observation Strategy for the Target Stars
Dongjie Tan, Jianghui Ji, Chunhui Bao +11
The Closeby Habitable Exoplanet Survey (CHES) constitutes a mission intricately designed to systematically survey approximately 100 solar-type stars located within the immediate pr…
Secular aberration drift in stellar proper motions: An additional term due to the change in line-of-sight direction
Niu Liu, Zi Zhu, Jia-Cheng Liu
The motion of the barycenter of the Solar System (SSB), the origin of the International Celestial Reference System, causes a directional displacement known as secular aberration. T…
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…
Test of source selection for constructing a more stable and uniform celestial reference frame
N. Liu, J. -C. Liu, Z. Zhu
We aim to evaluate the possibility of improving the ICRS realization starting from the ICRF2 catalogue by investigating the coordinate time series of radio sources observed by VLBI…
