| Abstract: | Results of the numerical simulation of spectra of the Pleiades brown dwarfs Calar 3 and Teide 1 are discussed. Synthetical
spectra were computed for several model atmospheres from a grid of Allard and Hauschildt (1995). From the comparison of computed
and observed spectra we have found that: – the spectrum of Teide 1 may be reasonably well fitted by JOLA in the visible region,
including the spectral regions around the Li I lines at λλ 670.8 and 812.6 nm. – The structure of absorption bands observed
in the spectrum of Teide 1 and Calar 3 depends mainly on Teff. The dependence on gravity is much weaker. – A comparison of observed and computed spectra shows that effective temperatures
of these Pleiades brown dwarfs is Teff ≈ 2900 K.
