thumbnail Fig. 1

CCD spectra of the recently classified SBS stars in the range 4100 − 7500  Å. Bottom panels: the two confirmed M stars; bars in the lowest panel indicate TiO bands common to both stars and VO bands of the late type; lines prominent in SBS 1444+503 are only reported in the corresponding panel. Upper panel: the dwarf carbon and the three CH stars; vertical bars indicate prominent features listed in the text. Bars corresponding to lines of particular interest for SBS 1310+561 are vertically shifted by 0.15 units above the others.

Medium-resolution spectra of the CH giant SBS 0759+533 and the dC SBS 1310+561. For this star an enlargment of the region 3900 − 4200 Å  from the lower resolution spectrum is plotted to emphasize Hδ and the CaII emissions, which are not covered by the grism #7 spectral range. Ordinates are the same as in Fig. 1.
