Contribution to the study of composite spectra - IX. Spectroscopic orbital elements of 10 systems* We present the results of a radial-velocity study of 10 spectroscopicbinaries with composite spectra that were observed at Observatoire deHaute-Provence with the CORAVEL instrument. Those systems, including acool, evolved, primary and a hot secondary of type B or A, were found tobe spectroscopic binaries. We computed their orbital elements for thefirst time. For three systems, the large mass function implies i~90°, with the possibility of eclipses. Mean angular separations arevery small (a<= 0.010 arcsec), which makes those systems resolvableonly with multi-pupil large interferometers.
