Gaia Early Data Release 3: Acceleration of the Solar System from Gaia astrometry
Astronomy and Astrophysics
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric solutions. Aims. The proper motions of QSO-like sources are used to reveal a systematic pattern due to the acceleration of the solar system barycentre with respect to the rest frame of the Universe. Apart from being an important scientific result by itself, the acceleration measured indoi:10.1051/0004-6361/202039734 fatcat:n7fd6mrqpnaddnrmnyqhbgigwu
