Secular Aberration Drift and IAU Definition of ICRS  

Authors / CoAuthors

Titov, O.

Abstract

The gravitational attraction of the Galactic centre leads to the centrifugial acceleration of the Solar system barycentre. It results in secular aberration drift which displaces the position of the distant radio sources. The effect should be accounted for in high-precision astrometric reductions as well as by the corresponding update of the ICRS definition.
