Spectroscopic analysis of RGB stars in nine open clusters
Saulo de Oliveira Cantanhêde, Alan Alves-Brito, Rodolfo Smiljanic +4
Stellar clusters are crucial tools for studying the age, spatial distribution, dynamics, kinematics, and chemical composition of different Galactic stellar populations. In this wor…
Planet engulfment in the chemically anomalous HD 129171/HD 129209 pair
Anne Rathsam, Jorge Meléndez, Rodolfo Smiljanic +2
Binary systems composed of stars with similar parameters should have identical chemical composition. However, many chemically anomalous pairs have been found in the literature, suc…
Milky Way disc & Bulge in situ populations: ESO white paper - Expanding horizons call
M. Bergemann, G. Kordopatis, G. Casali +11
The formation and evolution of the Milky Way's disc, bar, and bulge remain fundamentally limited by the lack of a contiguous, Galaxy-wide, high-precision chemo-dynamical map. Key o…
Carbon and nitrogen as indicators of stellar evolution and age. A homogeneous sample of 44 open clusters from the Gaia-ESO Survey
G. TautvaiÅ¡ienÄ, A. Drazdauskas, Å . Mikolaitis +11
Context. Low- and intermediate-mass giants undergo a complex chemical evolution that has yet to be observationally probed. The influence of core helium flash on the chemical compos…
Probing the origins. II. Unravelling lithium depletion and stellar motion: Intrinsic stellar properties drive depletion, not kinematics
M. L. L. Dantas, R. Smiljanic, D. Romano +4
In Paper I, we classified a stellar sample from the thin disc with a broad range in metallicity as being churned outward or inward, or blurred/undisturbed. In this paper (Paper II)…
Probing the origins. I. Generalised Additive Model inference of birth radii for Milky Way stars in the solar vicinity
M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2
We employ a Generalised Additive Model (GAM) to address the limitations inherent in radial metallicity gradients predicted by chemical evolution models, thereby facilitating the es…
