Abundances of neutron-capture elements in thin- and thick-disc stars in the solar neighbourhood
Gražina Tautvaišienė, Carlos Viscasillas Vázquez, Šarūnas Mikolaitis +4
The aim of this work is to determine abundances of neutron-capture elements for thin- and thick-disc F, G, and K stars in several sky fields near the north ecliptic pole and to com…
High-resolution spectroscopic study of dwarf stars in the northern sky: Na to Zn abundances in two fields with radii of 20 degrees
Šarūnas Mikolaitis, Arnas Drazdauskas, Renata Minkevičiūtė +6
New space missions, such as NASA TESS or ESA PLATO, will focus on bright stars, which have been largely ignored by modern large surveys, especially in the northern sky. Spectroscop…
The Gaia-ESO Survey: the N/O abundance ratio in the Milky Way
L. Magrini, F. Vincenzo, S. Randich +31
The abundance ratio N/O is a useful tool to study the interplay of galactic processes, e.g. star formation efficiency, time-scale of infall and outflow loading factor We aim to tra…
The Gaia-ESO survey: impact of extra-mixing on C- and N-abundances of giant stars
N. Lagarde, C. Reylé, A. C. Robin +30
The GES survey using FLAMES at the VLT has obtained high-resolution UVES spectra for a large number of giant stars, allowing a determination of the abundances of the key chemical e…
Stellar multiplicity in high-resolution spectroscopic surveys. I. Application to APOGEE subgiants and giants
Edita Stonkutė, Ross P. Church, Sofia Feltzing +1
Many field stars reside in binaries, and the analysis and interpretation of photometric and spectroscopic surveys must take this into account. We have developed a model to predict…
