Descripción
Selecting stars with previously measured or estimated rotational periods the authors measured Li equivalent widths in 8 stars of the Hyades late main sequence. Plotting log N(Li) against Rossby number the authors can separate the effects of temperature and rotation. They find for stars later than F8 increased depletion with longer period, at constant surface temperature. The authors give a tentative view of the implications of these results for stellar modelling.
