الملخص الإنجليزي

The study of the properties of the dwarf novae systems is a multiintroductory subject firstly; it can be taken from the point of view of a dwarf novae system, which leads to the outburst model.

That is biased on four main assumptions: the mass transfer burst, the disk instability, full limit cycle instability and thermal instability.

Secondly, the dwarf novae system can be regarded as stellar variables, where photometric variation are extrinsic rather than intrinsic in which these variation are connected to the mass transfer from the secondary star and same if geometrical aspect (radius ,mass ,orbital period ,mass rate ,distance of the white dwarf).

The aim of this work is to disclose the photometric and spectroscopic parameters of dwarf novae, inorder to understand the properties of this system.

Three dwarf novae systems have been treated, The first dwarf novae system (Wz sge) The second dwarf novae system (Ss cyg) The third dwarf novae system (Z cam) The outburst model is applied; the new parameters have been obtained in the case of super humps through the period of super outburst (Luminosity, temprature, disk radius,and accretion disk temperature gradient)
