Abstract (English):
Based on moderate-resolution spectra in the range 4200–5200 Å, we have studied late O and early B stars in the very young open star cluster IC 1805. The temperatures of the stars under the study have been derived by the differential method, in which simple parameters were chosen for a number of spectral lines and were then compared with the analogous parameters from an extensive sample of O–B stars. Accurate
