INVESTIGATION OF THE ATMOSPHERE OF THE SUPERGIANT HD14662 (F7IB)


The atmosphere of supergiant star HD14662 investigaed by using the atmosphere model method. By comparing the observed and theoretical values of the photometric indices β, [c1] and Q. The following values of parameters effective temperature and surfase gravity have been determined: Тeff=6250±200 К, logg=1,5±0.2. Theoretical values of the indices β, [c1] and Q were calculated by using Kurucz models. On the lines FeI has been investigated the parameter microturbulence (velocity). Found that for HD14662 star ξt=5км/с (FeI). By using the comparison calculated and observed values of equivalent widths of spectral lines has been determined the chemical composition of stars.
Found chemical compositions of star HD14662. The Chemical compositions is defined on the basis of comparison of the calculated and observable equivalent width of spectral lines. The calculations of equivalent width of spectral lines were spent by means of program DASA by developed in Kr.AO. The abundance of elements in the atmosphere of HD114662 star is close to the Sun, found that C is deficiency, Na is excess.
