Scientific paper

He I lines wavelength 5876 and wavelength 10830 were found in emission from several Be stars. The UV continuum above the ionization potential for He I is found to be enough to produce the observed emission only for stars earlier than B1 and to explain the observed emission for stars of later type, a source of helium ionizing photons is needed. It is shown that the EUV or X-ray photons from a binary compact companion star, accreting matter from the Be star gas envelope, can explain the observed He I line emission.
