The influence of non-LTE effects on the sodium abundance in the atmospheres of K giants.
Abstract
On the basis of non-LTE calculations, it is shown that the Na abundance in late G and K giants in the neighborhood of the sun is not conditioned by the effect of deviation from LTE. Instead, the Na abundance is conditioned by evolutionary processes. The Na abundances of eight K giants are specified.
