Adopting the astrometric data and line-of-sight velocities of main sequence stars from Gaia DR2, we present a detailed analytical study of stellar kinematics in the solar neighborhood. Based on an improved version of the Stromberg relation, we obtain a robust estimation of the solar peculiar ...
(Gaia DR2)on April 25,2018.The calculation ofstellar apparent position is extremelv important for astronomi—cal measurement and positioning.This paper complete the preprocessing for the Caia DR2 catalog and the matchingof Hipparcos and Gaia DR2.The difkrence of these two star catalogs at J...

The GaiaDR2 Process The new GaiaDR2 process provides access to the local Gaia DR2 database. It works as a server for scripts and modules, allowing them to perform arbitrary, thread-safe search operations on the entire Gaia DR2 catalog. GaiaDR2 can also be used as a standalone...
We use a modified method of the apparent motion parameters (AMP), in which the initial data from the Gaia DR2 catalog are not only high-precision coordinates, parallaxes, and radial velocities of the components of the studied wide binary stars, but are also their proper motions. The ...
This research makes use of the SIMBAD database and the Vizier catalog service, operated at CDS, Strasbourg, France. We also make heavy use of R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria (http://www.R-project.org/)....
