Lithium in K-supergiants.
Abstract
The lithium abundances in 20 K-supergiants are discussed. The highest values obtained are a factor of 10 less than the maximum values reached in stars. The ratio of the numbers of supergiants with high lithium abundances to those with low is consistent with that predicted by Iben's evolutionary tracks.
