Calibration of the [C/N] and [Y/Mg] chemical clocks with asteroseismic ages from the TESS space mission
E. Pakštienė, G. Tautvaišienė, V. Bagdonas +8
Context. Stellar ages are typically very difficult to estimate for field stars. New empirical methods, based on abundance ratios of chemical elements, are emerging and need to be c…
Detection of hot subdwarf binaries and sdB stars using machine learning methods and a large sample of Gaia XP spectra
M. Ambrosch, C. Viscasillas Vázquez, E. Solano +10
Hot subdwarfs (hot sds) are compact, evolved stars near the Extreme Horizontal Branch (EHB) and are key to understanding stellar evolution and the ultraviolet excess in galaxies. W…
Carbon and nitrogen as indicators of stellar evolution and age. A homogeneous sample of 44 open clusters from the Gaia-ESO Survey
G. Tautvaišienė, A. Drazdauskas, Š. 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…
Chemical composition of planetary hosts: II. Abundances of neutron-capture elements
A. Sharma, E. Stonkutė, A. Drazdauskas +4
We present a study of neutron-capture element abundances (Sr, Y, Zr, Ba, La, Ce, Nd, Pr, and Eu) in a large and homogeneous sample of 160 F-, G-, and K-type planet-host stars locat…
Chemical composition of planetary hosts: C, N, and -element abundances
A. Sharma, E. Stonkutė, A. Drazdauskas +4
Accurate atmospheric parameters and chemical composition of planet-hosting stars are crucial for characterising exoplanets and understanding their formation and evolution. Our obje…
Advanced Classification of Hot Subdwarf Binaries Using Artificial Intelligence Techniques and Gaia DR3 data
C. Viscasillas Vázquez, E. Solano, A. Ulla +11
Hot subdwarfs are compact blue evolved objects, burning helium in their cores surrounded by a tiny hydrogen envelope. Most models agree on a common envelope binary evolution scenar…
The Gaia-ESO Survey: The DR5 analysis of the medium-resolution GIRAFFE and high-resolution UVES spectra of FGK-type stars
C. C. Worley, R. Smiljanic, L. Magrini +42
The Gaia-ESO Survey is an European Southern Observatory (ESO) public spectroscopic survey that targeted stars in the Milky Way covering the major populations of the disk, bu…
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…
Atomic data for the Gaia-ESO Survey
Ulrike Heiter, Karin Lind, Maria Bergemann +27
We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Survey. We present an unprecedented effort to…
The Gaia-ESO Survey: Exploring the complex nature and origins of the Galactic bulge populations
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +36
Abridged: We used the fourth internal data release of the Gaia-ESO survey to characterize the bulge chemistry, spatial distribution, kinematics, and to compare it chemically with t…
The Gaia-ESO Survey: the chemical structure of the Galactic discs from the first internal data release
Š. Mikolaitis, V. Hill, A. Recio-Blanco +31
Most high-resolution spectroscopic studies of the Galactic discs were mostly confined to objects in the solar vicinity. Here we aim at enlarging the volume in which individual chem…
