ABUNDANCES of Na, Ca, Mg and Al in the ATMOSPHERES of K SUPERGIANTS of the SMALL MAGELLANIC CLOUD
The abundances of chemical elements Na, Ca, Mg and Al of the nine K-supergiants in SMC was investigated by a method of models of atmospheres. With this goal the CCD-spectrograms with high resolution was used. It is shown that all stars have a deficit abundances of iron from -0.40 to -0.97 dex relati...
