The cataclysmic variable SS Cygni

In this work we will try to give the most general panorama, comparatively with the conciseness, on SS Cygni which is the brightest dwarf nova.The dwarf novae form a sub-class of the more vaste panorama of the Cataclysmic Variables (CVs). For this reason firstly we will describe in general the CVs and the current theories which attempt to describe their physical behaviour (Sections 2 and 3). The up-to-date observational properties of SS Cygni (Section 4) and a discussion on their explanation within the framework of theories (Section 5) will allow us to draw the conclusions (Section 6) and to argue the most convenient line of investigation (Section 7) both experimental and theoretical for a better understanding of the underlying physics of these systems.
