Balmer decrements in dwarf novae
Astrophysical Bulletin, 2017We investigate the question of the possible variable conditions in dwarf novae. The Balmer decrements are used as variability indicators due to their form being strongly dependent on the conditions in the radiating medium. It is shown that the decrements are usually anomalous and variable in time at minimum light, which indicates a variability of the ...

Outbursts of Southern Dwarf Novae
International Astronomical Union Colloquium, 1979Abstract.The mean cycles and types of maxima for a number of dwarf novae are tabulated. It is shown that supermaxima are not confined to dwarf novae of short mean cycles. The decline rates for some stars are examined to ascertain if the orbital period, accurate to within ten percent, could be derived from visual observations. It is shown that, at least

With the recent detection of radio emission from dwarf novae a new channel of information on these semi-detached binaries has opened. The radiation is variable within days and highly polarized. Most likely it is emitted by some gyromagnetic process, which would allow to estimate the magnetic field.

Automatic Classification of Dwarf Nova
2019Dwarf nova is an abundant subtype of cataclysmic variable star with frequent eruptions. This binary star is a semi-close binary system consisting of a late dwarf secondary star with loch lobes and a White Dwarf host star. Finding more dwarf novae can help us to study the dynamic evolution of the system and many complex physical processes.
