The Gaia-ESO survey: placing constraints on the origin of r-process elements
M. Van der Swaelmen, C. Viscasillas Vázquez, G. Cescutti +19
A renewed interest about the origin of \emph{r}-process elements has been stimulated by the multi-messenger observation of the gravitational event GW170817, with the detection of b…
Chemical Composition Of Bright Stars In The Northern Hemisphere: Star-Planet Connection
G. Tautvaišienė, Š. Mikolaitis, A. Drazdauskas +12
In fulfilling the aims of the planetary and asteroseismic research missions, such as that of the NASA Transiting Exoplanet Survey Satellite (TESS) space telescope, accurate stellar…
The Gaia-ESO Survey: Age-chemical-clock relations spatially resolved in the Galactic disc
C. Viscasillas Vázquez, L. Magrini, G. Casali +33
The last decade has seen a revolution in our knowledge of the Galaxy thanks to the Gaia and asteroseismic space missions and the ground-based spectroscopic surveys. To complete thi…
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…
Stellar multiplicity in the Milky Way Galaxy
Edita Stonkute, Ross P. Church, Sofia Feltzing +1
We present our models of the effect of binaries on high-resolution spectroscopic surveys. We want to determine how many binary stars will be observed, whether unresolved binaries w…
On the metallicity dependance of the [Y/Mg] - age relation for solar type stars
S. Feltzing, L. M. Howes, P. J. McMillan +1
Several recent studies of Solar twins in the Solar neighbourhood have shown a tight correlation between various elemental abundances and age, in particular [Y/Mg]. If this relation…
Stellar substructures in the solar neighbourhood IV. Kinematic Group 1 in the Geneva-Copenhagen survey
R. Ženovienė, G. Tautvaišienė, B. Nordström +2
We determine detailed elemental abundances in stars belonging to the so-called Group 1 of the Geneva-Copenhagen survey (GCS) and compare the chemical composition with the Galactic…
Stellar substructures in the solar neighbourhood. III. Kinematic group 2 in the Geneva-Copenhagen survey
R. Ženovienė, G. Tautvaišienė, B. Nordström +1
From correlations between orbital parameters, several new coherent groups of stars were recently identified in the Galactic disc and suggested to correspond to remnants of disrupte…
Stellar substructures in the solar neighbourhood. I. Kinematic group 3 in the Geneva-Copenhagen survey
E. Stonkutė, G. Tautvaišienė, B. Nordström +1
Galactic Archeology is a powerful tool for investigating the formation and evolution of the Milky Way. We use this technique to study kinematic groups of F- and G-stars in the sola…
