The Gaia-ESO Survey: 3D dynamics of young groups and clusters from GES and Gaia EDR3

Autor: Wright, Nicholas J., Jeffries, R. D., Jackson, R. J., Sacco, G. G., Arnold, Becky, Franciosini, E., Gilmore, G., Gonneau, A., Morbidelli, L., Prisinzano, L., Randich, S., Worley, Clare C.

We present the first large-scale 3D kinematic study of ~2000 spectroscopically-confirmed young stars (<20 Myr) in 18 star clusters and OB associations (hereafter groups) from the combination of Gaia astrometry and Gaia-ESO Survey spectroscopy. We mea

The Gaia-ESO Survey: Empirical estimates of stellar ages from lithium equivalent widths (EAGLES)

Autor: Jeffries, R. D., Jackson, R. J., Wright, Nicholas J., Weaver, G., Gilmore, G., Randich, S., Bragaglia, A., Korn, A. J., Smiljanic, R., Biazzo, K., Casey, A. R., Frasca, A., Gonneau, A., Guiglion, G., Morbidelli, L., Prisinzano, L., Sacco, G. G., Tautvaišienė, G., Worley, C. C., Zaggia, S.

We present an empirical model of age-dependent photospheric lithium depletion, calibrated using a large, homogeneously-analysed sample of 6200 stars in 52 open clusters, with ages from 2--6000 Myr and $-0.3<{\rm [Fe/H}]<0.2$, observed in the Gaia-ESO

The disk mass is among the most important input parameter for every planet formation model to determine the number and masses of the planets that can form. We present an ALMA 887 mu m survey of the disk population around objects from similar to 2 to

With its origin coming from several sources (Big Bang, stars, cosmic rays) and given its strong depletion during its stellar lifetime, the lithium element is of great interest as its chemical evolution in the Milky Way is not well understood at prese
