Astronomical distance scales in the Gaia era
arXiv:1906.09040 · doi:10.1016/j.crhy.2019.02.001
Abstract
Overview of the determination of astronomical distances from a metrological standpoint. Distances are considered from the Solar System (planetary distances) to extragalactic distances, with a special emphasis on the fundamental step of the trigonometric stellar distances and the giant leap recently experienced in this field thanks to the ESA space astrometry missions Hipparcos and Gaia.
