Scientific paper

The period variation (k) and orbital elements, such as the epoch period and radial velocity, are computed for the two spectroscopic noneclipsing binaries using data published by Walker and Chincarini (1968), and Smak (1969) for the SS Cygni and data from Chincarini and Walker (1980), and Joy (1954) for the AE Aquarii. The SS Cygni k value is significant to about a 5 standard deviation, while the AE Aquarii k value is significant to about 0.5 standard deviation. The various data are compared and the main characteristics of both binary systems are summarized.
