Abstract

Observations of the 6707.8 Å Li I line in a sample of active binary systems have been carried out at the Calar Alto Observatory with the 2.2m telescope. In addition, some single stars with different chromospheric activity levels have also been observed mainly for comparison purposes.

Gaussian fits have been performed in order to separate the Fe I Une at 6707.4 Å which is usually blended with the Li I line.

A curve-of-growth method has been used to derive Li abundances. The results are discussed according to the activity levels.
