Abstract

Spectra of the spots in the region of the lithium 6708 Å line and some FeI and CaI lines have been observed. The observations were carried out with CCD-camera in May, June and July 2007 at the telescope TST-2 of the Crimean Astrophysical Observatory. The spot models were calculated using the observed profiles of FeI and CaI lines. The lithium abundance was obtained using the calculated spot models and observed LiI 6708 Ǻ line profiles. The result is lg(NLi) = 1.20, 1.15 and 1.00 (in scale lgA(H) = 12).
