A spectroscopic study of the peculiar stars μ Lep and χ Boo

Abstract

On the basis of Coudé material generously loaned by Dr. H. Babcook, about 250 lines were measured in the wavelength region λ ∼ 3800 - 4600. A 94 % of them were identified. Of this percentage, 40 % belong to Mn II. In both stars C II is too strong for this type. P II was not detected. Y II is surprisingly strong, with a slight difference in the enhancement between both stars. The stars were also compared with two other manganese stars already analysed at high dispersion. The full paper will be published somewhere else.
