Stellar ages from [C/N] in giant stars: applicability and limitations
Giada Casali, Luca Casagrande, Fiorenzo Vincenzo +5
The [C/N] abundance ratio is a powerful age indicator for giant stars, enabling age estimates for spectroscopic samples where traditional methods are limited. We calibrate a multiv…
The non-LTE abundances of magnesium and yttrium and asteroseismic ages for the chemical clock calibration
Š. Mikolaitis, G. Tautvaišienė, E. Pakštienė +11
Building on our previous study, which demonstrated the importance of accounting for departures from local thermodynamic equilibrium (LTE) in elemental-abundance determinations and…
Astrometric and Spectroscopic Analysis of IC 2714: An Open Cluster Hosting a Lithium-Rich Giant
T. Flaulhabe, N. Holanda, G. Tautvaišienė +7
Open clusters serve as laboratories to study and evaluate stellar evolution and Galactic chemical evolution models. Chemical peculiarities, such as lithium-rich giants, are rarely…
Chromospherically active stars: Lithium and CNO abundances in northern RS CVn stars
B. Bale, G. Tautvaisiene, R. Minkeviciute +4
Aims: We carried out a detailed investigation of Lithium and CNO abundances, including carbon isotope ratios, in RS CVn stars to assess the role of magnetic activity in the mixing…
Chromospherically active stars: Chemical composition of photospheres in 20 RS CVn stars
B. Bale, G. Tautvaisiene, R. Minkeviciute +4
Context. Various element transport processes modify the photospheric chemical composition of low-mass stars during their evolution. The most prominent one is the first dredge-up th…
Metal-THINGS: The Milky Way twin candidate NGC 3521
L. S. Pilyugin, M. A. Lara-Lopez, G. Tautvaisiene +6
The 3D spectrophotometry measurements of the galaxy NGC~3521, a structural Milky Way analogue (sMWA), were carried out within the Metal-THINGS project. We found that the oxygen abu…
