Scientific paper

The 36 spectroscopic exposures obtained for the 0.24-day eclipsing binary RW Com since 1977 have allowed the velocities and emission behavior of the components to be studied. This work arose from the need to obtain a mass ratio for synthetic light curve analysis which could in turn furnish system models for use in studies of the system's light curves. Radial velocities were determined by means of the cross correlation method, and a mass ratio m(2)/m(1) of 0.34 + or - 0.02 has been obtained. Since star 2 is eclipsed at primary minimum, it is identified as the less massive component.
