The 10 parsec sample in the Gaia era: first update

C. Reyle, K. Jardine, P. Fouque +3

The nearest stars provide a fundamental constraint for our understanding of stellar physics and the Galaxy. The nearby sample serves as an anchor where all objects can be studied a…

Deciphering the evolution of the Milky Way discs: Gaia APOGEE Kepler giant stars and the Besançon Galaxy Model

N. Lagarde, C. Reylé, C. Chiappini +13

We investigate the properties of the double sequences of the Milky Way discs visible in the [/Fe] vs [Fe/H] diagram. In the framework of Galactic formation and evolution, we dis…

Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds

Gaia Collaboration, X. Luri, L. Chemin +417

We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…

The search for extratidal star candidates around Galactic globular clusters NGC 2808, NGC 6266, and NGC 6397 with {\textit{Gaia}} DR2 astrometry

Richa Kundu, Camila Navarrete, José G. Fernández-Trincado +5

Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and…

Kinematics and dynamics of Gaia red clump stars

Jean-Baptiste Salomon, Olivier Bienaymé, Céline Reylé +2

We analyse the kinematics and dynamics of a homogeneous sample of red clump stars selected from the second Gaia data release catalogue in the direction of the Galactic poles. The l…

The hidden past of M92: Detection and characterization of a newly formed 17° long stellar stream using the Canada-France Imaging Survey

Guillaume F. Thomas, Jaclyn Jensen, Alan McConnachie +17

We present an analysis of the structure, kinematics and orbit of a newly found stellar stream emanating from the globular cluster M92 (NGC 6341). This stream was discovered in an i…
