The Pristine survey X: a large population of low-metallicity stars permeates the Galactic disk
Federico Sestito, Nicolas F. Martin, Else Starkenburg +26
The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that these low-metallicity st…
The Pristine Survey -- VI. The first three years of medium-resolution follow-up spectroscopy of Pristine EMP star candidates
David S. Aguado, Kris Youakim, Jonay I. González Hernández +27
We present the results of a 3-year long, medium-resolution spectroscopic campaign aimed at identifying very metal-poor stars from candidates selected with the CaHK, metallicity-sen…
Exploring circumstellar effects on the lithium and calcium abundances in massive Galactic O-rich AGB stars
V. Pérez-Mesa, O. Zamora, D. A. García-Hernández +6
We previously explored the circumstellar effects on the Rb and Zr abundances in massive Galactic O-rich AGB stars. Here we are interested in the role of the extended atmosphere in…
Ca line formation in late-type stellar atmospheres: I. The model atom
Y. Osorio, K. Lind, P. S. Barklem +2
Context. Departures from local thermodynamic equilibrium (LTE) distort the calcium abundance derived from stellar spectra in various ways, depending on the lines used and the stell…
