Stellar Population Astrophysics (SPA) with the TNG. CNO abundances in 28 open clusters
Bruno Ćurjurić, Arnas Drazdauskas, Gražina Tautvaišienė +4
Aims. Our main aim with this work was to enlarge the pool of open clusters with determined carbon, nitrogen, and oxygen abundances in evolved giants to further advance chemical clo…
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…
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…
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…
The Gaia-ESO survey: A spectroscopic study of the young open cluster NGC 3293
T. Morel, A. Blazère, T. Semaan +24
We present a spectroscopic analysis of the GIRAFFE and UVES data collected by the Gaia-ESO survey for the young open cluster NGC 3293. Archive spectra from the same instruments obt…
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…
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…
The Gaia-ESO Survey: age spread in the star forming region NGC6530 from the HR diagram and gravity indicators
L. Prisinzano, F. Damiani, V. Kalari +33
In very young clusters, stellar age distribution is the empirical proof of the duration of star formation (SF) and of the physical mechanisms involved in the process. We derived ac…
The Gaia-ESO Survey: Evidence of atomic diffusion in M67?
C. Bertelli Motta, A. Pasquali, J. Richer +37
Investigating the chemical homogeneity of stars born from the same molecular cloud at virtually the same time is very important for our understanding of the chemical enrichment of…
Chemical composition of giant stars in the open cluster IC 4756
Vilius Bagdonas, Arnas Drazdauskas, Gražina Tautvaišienė +2
Context: Homogeneous investigations of red giant stars in open clusters contribute to studies of internal evolutionary mixing processes inside stars, which are reflected in abundan…
The Gaia-ESO Survey: chemical signatures of rocky accretion in a young solar-type star
L. Spina, F. Palla, S. Randich +23
It is well known that newly formed planetary systems undergo processes of orbital reconfiguration and planetary migration. As a result, planets or protoplanetary objects may accret…
