Helium peculiar stars in the red spectral region.

ANDRILLAT Y. and JASCHEK C.

Abstract (from CDS):

Based upon 33A/mm dispersion spectroscopic material we examine if equivalent widths of H and He lines can be used for the detection of new helium-peculiar stars. The answer is affirmative and we present some new candidates discovered this way. We have also investigated if the use of different helium lines than those of the 3D series (4026, 4471) modifies the assignments of helium peculiar stars. This is not the case, since the use of λ6678 (1D) and λ7065 (3S) gives the same results.
