The determination of C, N, and O abundances in late-type star atmospheres - Extremum problem
Abstract
The possibility of determining carbon, nitrogen, and oxygen abundances through the extremum problem treatment is discussed. The minimized functional consists of differences between observed and calculated parameters of atomic and molecular absorption lines or their blends. A brief description of the procedure and C, N, and O abundance data for the atmosphere of a K giant are presented.
