In this paper we analyze the class of Cataclysmic Variables (CVs) as sources of Gravitational Radiation, basing our analysis only on known objects (168 CVs taken from the recent Ritter Catalog), as we have already done in two previous papers for two other classes of astrophysical objects, eccentric binaries and pulsars. We try to evaluate the Gravitational Wave background, outlining all the potentially interesting sources, in two different ways, showing the substantial agreement of the results obtained. Although not completely new, such results are based on real samples of data, plus some statistical analysis, and therefore constitute a solid basis for planning the construction of GW detectors (especially space-borne GW antennas). Moreover, they provide the possibility of experimentally proving the effectiveness of the mechanism of Gravitational Radiation on CV evolution. Furthermore, for the sake of completeness, the GW emission from the known low-mass X-ray binaries and CV related objects has been evaluated.

Abstract
In this paper we analyze the class of Cataclysmic Variables (CVs) as sources of Gravitational Radiation, basing our analysis only on known objects (168 CVs taken from the recent Ritter Catalog), as we have already done in two previous papers for two other classes of astrophysical objects, eccentric binaries and pulsars. We try to evaluate the Gravitational Wave background, outlining all the potentially interesting sources, in two different ways, showing the substantial agreement of the results obtained. Although not completely new, such results are based on real samples of data, plus some statistical analysis, and therefore constitute a solid basis for planning the construction of GW detectors (especially space-borne GW antennas). Moreover, they provide the possibility of experimentally proving the effectiveness of the mechanism of Gravitational Radiation on CV evolution. Furthermore, for the sake of completeness, the GW emission from the known low-mass X-ray binaries and CV related objects has been evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
