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…
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…
