"Details of the Hertzsprung-Russell diagram as revealed by the 2nd Gaia data release"

I will briefly review the Gaia satellite mission and how the data from this mission allow us to establish, with much greater accuracy than ever before, critical relations between observed properties of stars. I will
show in particular the details that have now come into focus for the Hertzsprung-Russell diagram, which shows relations between stellar surface temperature and brightness for stars of different ages, masses
and chemical composition, and which is as such a vital tool in understanding stellar structure and evolution.
