The primary conflict between studies attempting to measure 6Li in stars harboring planets, a potential indicator of planet formation, is the incompleteness and inaccuracy of current line lists for the lithium region. We are attempting to resolve these issues using very high-resolution (R ∼ 120,000) and very high quality (S/N between 250 and 1000) spectra of stars with a range of abundances.
