Low State of Radiation in Emission Spectrum of the Star MWC361
Abstract
Results of spectral researches of spectral-binary Be Herbig type star MWC361 are presented. Observational phases are corresponding to the minimum of the radial velocity curve of the system. Emission hydrogen lines Hα and Hβ show the low condition of radiation. First time in the spectrum we haved is covered diffuse interstellar bands DIB λλ 5780, 5797 Å. For 3 months of observations we have discovered a considerable increase of relative intensities of emission lines components of hydrogen and in emission lines Si λλ 6347 6371 Å and [OI] λλ 6300, 6363 Å.
