Outbursts of dwarf novae [PDF]
A review is given of the observational facts related to the outbursts of dwarf novae and of relevant aspects of the theory of accretion disks. It now appears possible to explain the outbursts of dwarf novae in terms of a nonstationary accretion behavior. Between the outbursts, the material supplied by the secondary component is stored in the relatively

Temperatture esttiimattiion off EXDRA and SSUMI dwarff Nova systtems from spectroscopic data
The seasonal behavior of the light curve for selected star SS UMI and EXDRA during outburst cycle is studied. This behavior describes maximum temperature of outburst in dwarf nova.

Recent work on the physical processes resulting from mass transfer between the red and blue components of dwarf nova binaries is reviewed. The optical behaviour of the blue component's accretion disc suggests that it may be the infall, accretion energy which is being liberated during outbursts.

Observations of Dwarf Novae [PDF]
Spectroscopic and photometric observations relevant to the structure of classical novae, recurrent novae and dwarf novae are collected together. Details are given of optical, infrared, satellite ultraviolet, X-ray and radio observations. Most of these can be understood in terms of the hot spot model of cataclysmic variable stars.

Relation between Long-term Activity and Luminosity of the Pre- and Post-novae CT Ser and V446 Her
We show a relation of the pre- and post-nova activity of CT Ser (nova 1948) and V446 Her (nova 1960), known to have remarkably similar orbital periods P _orb . We use both photographic and CCD photometric observations.

Systematics of Dwarf Novae [PDF]
AbstractFrom about 30 Dwarf Novae with the best determined distances the following relationships are found.(i)a tight correlation between absolute magnitude at maximum light, Mv (max), and orbital period, P.(ii)a correlation between Mv (min) and P showing wide scatter.(iii)a correlation between Mv (mean), the mean absolute magnitude averaged over ...

V2487 Oph 1998: a post nova in an intermediate polar
V2487 Oph (Nova Oph 1998) is a classical nova that exploded in 1998. XMM-Newton observations performed between 2 and 9 years after the explosion showed emission related to restablished accretion, and indicative of a magnetic white dwarf.

SWSex Stars, Old Novae, and the Evolution of Cataclysmic Variables
The population of cataclysmic variables with orbital periods right above the period gap are dominated by systems with extremely high mass transfer rates, the so-called SW Sextantis stars.
