A detailed study of lithium in 107 CHEPS dwarf stars
2018
Astronomy and Astrophysics
We report results from lithium abundance determinations using high resolution spectral analysis of the 107 metal-rich stars from the Calan-Hertfordshire Extrasolar Planet Search programme. We set out to understand the lithium distribution of the population of stars taken from this survey. The lithium abundance with account NLTE effects was determined from the fits to the Li I 6708 Å resonance doublet profiles in the observed spectra. We find that a) fast rotators tend to have higher lithium
