Scientific paper

A new orbit solution for CV Serpentis is presented based on 34 coude and 18 Cassegrain spectrograms. The system consists of a WC8 plus 08 minus 09 III-V pair of approximately equal bright stars, with minimum masses of 11 solar masses and 22 solar masses, respectively. The spectral type and minimum mass of the O star suggest that the orbital inclination is not greater than 65 deg; thus the WC8 star has a mass in the range 11-14 solar masses. The evolutionary implications of these results are considered.
