VizieR Online Data Catalog: Chemical abundances of solar analogues (Adibekyan+, 2016)
Abstract
To understand if the abundance trend observed with the condensation temperature is a function of Galactocentric distances for a fixed age of stars, we selected about 40 stars with ages similar to that of the Sun but with different mean Galactocentric distances from the Geneva-Copenhagen Survey sample (GCS, Nordstroem et al., 2004A&A...418..989N, Cat. V/117): with the smallest (Rmean~6.5kpc), largest (Rmean~9kpc), and solar (Rmean~8kpc) Galactocentric Rmean values.
High-resolution and high signal-to-noise (S/N) spectra for these stars were obtained by performing new observations with HARPS (22 stars) and UVES (six stars) ESO spectrographs, and by extracting spectra for 14 stars from the ESO archive. The file param.dat lists the stellar parameters of the stars. The file abund.dat lists the derived abundances of the elements for each star. (2 data files).- Publication:
