The Complexity of the Cetus Stream Unveiled from the Fusion of STREAMFINDER and StarGO
Zhen Yuan, Khyati Malhan, Federico Sestito +16
We combine the power of two stream-searching tools, STREAMFINDER and StarGO applied to the Gaia EDR3 data, to detect stellar debris belonging to the Cetus stream system that forms…
Young giants of intermediate mass Evidence of rotation and mixing
Linda Lombardo, Patrick François, Piercarlo Bonifacio +7
In the search of a sample of metal-poor bright giants using Str{ö}mgren photometry, we serendipitously found a sample of 26 young (ages younger than 1 Gyr) metal-rich giants, some…
The metal-poor end of the Spite plateau. II. Detailed chemical investigation
A. Matas Pinto, M. Spite, E. Caffau +7
Context. The study of old, metal-poor stars deepens our knowledge on the early stages of the universe. In particular, the study of these stars gives us a valuable insight into the…
The Pristine survey XIV: chemical analysis of two ultra-metal-poor stars
C. Lardo, L. Mashonkina, P. Jablonka +15
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultr…
Sulfur abundances in the Galactic bulge and disk
F. Lucertini, L. Monaco, E. Caffau +2
Context. The measurement of -elements abundances provides a powerful tool to put constraints on chemical evolution and star formation history of galaxies. The majority of studie…
Gaia Early Data Release 3: Updated radial velocities from Gaia DR2
G. Seabroke, C. Fabricius, D. Teyssier +40
Gaia's Early Third Data Release (EDR3) does not contain new radial velocities because these will be published in Gaia's full third data release (DR3), expected in the first half of…
