Ultracool dwarfs
Yakiv V. Pavlenko
We present results of modeling of spectra of M-, L-, T-dwarfs. Theoretical spectra are fitted to observed spectra to study the main parameters of the low-mass objects beyond the bo…

On the Interpretation of the Optical Spectra of L-type Dwarfs
Ya. Pavlenko, M. R. Zapatero Osorio, R. Rebolo
We present synthetic optical spectra in the range 640-930 nm of a sample of field L dwarfs and the brown dwarf GL229B. Our computations show that Li, Na, K, Rb, and Cs govern the s…

Theoretical LTE & NLTE curves of growth for Li I lines in G-M dwarfs and subgiants
Ya. V. Pavlenko, A. Magazzu
Detailed simultaneous radiative transfer-statistical equilibrium calculations have been performed for lithium in atmospheres of solar metallicity G-M dwarfs and subgiants. Model at…
