Young Stars in the Camelopardalis Dust and Molecular Clouds. IV. Spectral Observations of the Suspected YSOs

英文摘要：

In the first three papers of this series, about 200 objects in Camelopardalis and the nearby areas of Cassiopeia, Perseus and Auriga were suspected of being pre-main-sequence stars in different stages of evolution. To confirm the evolutionary status of the 15 brightest objects, their far-red range (600--950 nm) spectra were obtained. Almost all these objects are young stars with emissions in H alpha, OI, CaII and P9 lines. The equivalent widths of emission lines and approximate spectral classes of the objects are determined.
