Scientific paper

Results are given on a spectral classification of 316 stars and objects having a continuous spectrum, selected in the course of the Second Byurakan Spectral Sky Survey. Slit spectra are used, obtained from 1978 to 1994, predominantly on the 6-m telescope of the Special Astrophysical Observatory, Russian Academy of Sciences, with a resolution of 5-15 Å. The sample contains objects in the range of stellar magnitudes 10.12 ≤ m(pg) ≤ 19.5. We found 114 DA, 13 DB, 4 DC, and 1 DQ white dwarfs, 57 sdB and 13 sdO subdwarfs, 12 NHB, 10 cataclysmic variables, 76 stars of late spectral types, 3 spectroscopic binary systems, and 13 objects with a continuous spectrum. Several recordings are given for each of these spectral types.
