The Gaia mission

T. Prusti, +624 more
TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.
Journal ArticleDOI

Gaia Data Release 2: Observational Hertzsprung-Russell diagrams

C. Babusiaux, +451 more
TL;DR: In this article, the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD) was highlighted, depending in particular on stellar population selections.
Journal ArticleDOI

Gaia Data Release 2. Kinematics of globular clusters and dwarf galaxies around the Milky Way

Amina Helmi, +484 more
TL;DR: In this paper, the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way is demonstrated. But the accuracy of the errors, statistical and systematic, are relatively well understood.
Proceedings ArticleDOI

4MOST - 4-metre Multi-Object Spectroscopic Telescope

TL;DR: The 4MOST project as mentioned in this paper proposes a wide-field (3 square degree, goal >5 square degree), high-multiplex (1500 fibres, goal 3000 fibres) spectroscopic survey facility for an ESO 4m-class telescope.
Proceedings ArticleDOI

The 4MOST instrument concept overview

TL;DR: An overview of the 4MOST systems: optomechanical, control, data management and operations concepts; and initial performance estimates are provided.
