Abstract: In this work, the fundamental atmospheric parameters (effective temperature $T_\text{eff}$, surface gravity $\mathrm{log}\, g$, microturbulent velocity $V_\text{mic}$) of the group of A–F-type stars have been determined. Main sequence and supergiant stars in the temperature range of 6000–9000 K have been included in the group of stars under study. The obtained fundamental parameters are necessary for chemical abundance calculation using atmosphere modeling approach. The comparison with the published values of the parameters determined by other authors has been performed. The differences with the published values are within the accidental errors of parameters determination.

Keywords: A–F-type stars, fundamental parameters of atmospheres.
