Barium abundance in Galactic Cepheids
Listed in IVOA Registry (Virtual Observatory)
Using an Non-Local Thermodynamic Equilibrium (NLTE) analysis and a homogenous spectral data base, we have determined Ba abundances in a sample of 210 Galactic Cepheids and related objects.
Description
We confirm the previous result reported in Andrievsky et al. that the barium distribution in the range of Galactocentric distances from 5 to 18kpc shows very small gradient value. The value determined here - d[Ba/H]/dR~-0.01dex/kpc - is smaller than that for other s-process elements, such as La, Pr, Nd and Sm (Luck & Lambert, 2011AJ....142..136L, Cat.
J/AJ/142/136), that typically show gradients of -0.03dex/kpc.
