| Abstract: | The light curves of 30 well observed W UMa-type systems are analysed according to Kopal's method for the study of the light changes of eclipsing variables by using frequencydomain techniques. New geometric and photometric elements are derived and new values for the gravity-darkening coefficients are also given. Finally, an answer to the problem of whether or not these are contact systems is attempted. |
