Scientific paper

High-resolution spectra have been obtained for seven solar-type stars in Praesepe. Previous observations suggested that Praesepe stars have much more lithium than Hyads of the same color, despite these two clusters having the same age. The present observations show that Praesepe stars and Hyads have essentially the same Li equivalent widths, consistent with the view that stars of the same mass deplete Li at the same rate.
