Abstract

The generalized scale of effective temperatures (Teff) for substars and main sequence stars in the interval spectral types Sp = O8V ÷ T9,5V. Determined the dependence of effective temperatures Teff from spectral code CSp for Sp = O8V ÷ T9,5V. Approximation executed depending lg Teff - CSp polynomial the fifth power, the relative error free members are less than 17%.

Keywords: stars; substars; scale of effective temperatures
