Abstract:
A theoretical study of the mass transfer process of non-magnetic cataclysmic variable
(CV) stars was carried out. 11 CV systems were selected in different subcategories
of CVs and the orbital period analyzing process was performed using both Fourier
and Lomb-Scargle algorithms to determine which algorithm generated the best results
of periodicity for the obtained light curves of these selected samples. The percentage
error of the determination of the orbital period for both algorithms was discussed.
The calculated orbital periods of the above sample of CVs were then used for the
determination of the mean temperature of the accretion disks of these CVs by using the
techniques explained in spectroscopic Balmer emission lines and Stromgren photometry
observations. Finally, a correlation was obtained between mass transfer rates which were
determined using various techniques and algorithms and the mean temperature of the
accretion disk.
