Among new results for more massive stars it is necessary to note a study of the overionization effect of C II, N II and O II ions for early B stars and a construction of a new method of the effective temperature determination for G and K giants and supergiants. A search of exoplanets around K giants led to a discovery of the planets for three more stars of this type. Product Description popup.authors Антонюк К.А. Артеменко С.В. Бабіна О.В. Гранкін К.М.
