... Hyades ( Soderblom et al . 1990 ) . This pattern leads to the conclusion that diffusion requires 0.1 to 0.2 Gyr to develop and to deplete the atmospheric Li before it can produce a well - defined dip among main - sequence stars . Since ...

... Hyades Li chasm . At the 0.064 dex level , there is no sign of a difference between [ Fe / H ] for the Hyades dwarfs and giants . At low resolution , the D strong - feature index of Taylor and Johnson ( 1987 ) is anomalously weak in the ...
