The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. I. Cluster age range and initial membership selections
M. L. Gutiérrez Albarrán, D. Montes, M. Gómez Garrido +33
Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent but also shows a complex pattern with other parameters that is not yet unders…
The Pristine survey III: Spectroscopic confirmation of an efficient search for extremely metal-poor stars
K. Youakim, E. Starkenburg, D. S. Aguado +13
The Pristine survey is a narrow-band, photometric survey focused around the wavelength region of the Ca II H & K absorption lines, designed to efficiently search for extremely meta…
WHT follow-up observations of extremely metal-poor stars identified from SDSS and LAMOST
D. S. Aguado, J. I. González Hernández, C. Allende Prieto +1
We have identified several tens of extremely metal-poor star candidates from SDSS and LAMOST, which we follow-up with the 4.2m WHT telescope to confirm their metallicity.We follow…
CNO behaviour in planet-harbouring stars. I Nitrogen abundances in stars with planets
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Carbon, nitrogen, and oxygen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation and evolut…
Ret, its debris disk, and its lonely stellar companion Ret. Different trends for different spectra
V. Adibekyan, E. Delgado-Mena, P. Figueira +8
Several studies have reported a correlation between the chemical abundances of stars and condensation temperature (known as Tc trend). Very recently, a strong Tc trend was reported…
Oxygen and Magnesium Abundance in the Ultra-Metal-Poor Giants CS22949-037 and CS29498-043: Challenges in Models of Atmospheres
G. Israelian, N. Shchukina, R. Rebolo +3
We report the results of a non-LTE Fe, O and Mg abundance analysis of the carbon-nitrogen-rich ultra-metal-poor giants CS29498--043 and CS22949--037. The abundance of oxygen has be…
