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…
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…
