In this work, we determine the chemical composition of the atmospheres of the group of 13 A–F-stars. The group consists of main sequence and supergiant stars in the temperature range of 6000–9000 K. We analyze the chemical abundance patterns for 25 elements depending on atomic number. In conclusion, we state the non-uniform nature of chemical peculiarities in the atmospheres of Am-stars in the temperature range of 7000–9000 K and show that there are no chemical peculiarities (similar to Am-stars) in the atmospheres of F-supergiants, which indicates that they are disappearing in the turbulent atmospheres.
Keywords:
A–F-type stars, chemical composition of atmospheres.
