Stars: Sky Surveys, Stars: Spectral Classification
Scientific paper
The results of the spectra/classification of 310 stars and objects having a continuous spectrum, selected in the course of the Second Byurakan Spectral Sky Survey, are given. Slit spectra were used in the work, which were obtained from 1978 to 1994, mainly on the 6-m telescope of the Special Astrophysical Observatory, Russian Academy of Sciences; some of the spectra were obtained on the 2.6-m telescope of the Byurakan Astrophysical Observatory, National Academy of Sciences of Armenia, and the 4.5-m Multiple-Mirror Telescope (USA), with 5-15 Å resolution. The sample contains objects in the range of stellar magnitudes 11.0 ≤ m(pg) ≤ 19.5. We found 93 DA, 2 DO, 12 DB, and 1 DC white dwarfs, 83 sdB and 20 sdO subdwarfs, 34 NHB variables, 2 cataclysmic variables, 48 stars of late spectral types, 8 spectroscopic binary systems, and 7 objects having a continuous spectrum. Several recordings are given for each of these spectral types.
