The Kukarkin-Parenago Relation for Dwarf Novae and Novae [PDF]
Astrophysics and Space Science, 1987 AbstractThe period-amplitude relation and the period-energy relation for dwarf novae and novae are discussed. The total outbursts energy is shown to be a more suitable characteristic of the outburst than its amplitude.

AT Cnc: A SECOND DWARF NOVA WITH A CLASSICAL NOVA SHELL [PDF]
The Astrophysical Journal, 2012 We are systematically surveying all known and suspected Z Cam-type dwarf novae for classical nova shells. This survey is motivated by the discovery of the largest known classical nova shell, which surrounds the archetypal dwarf nova Z Camelopardalis.

Modeling the EUV spectra of optically thick boundary layers of dwarf novae in outburst [PDF]
, 2014 Here we compute detailed model spectra of recently published optically thick one-dimensional radial baundary layer (BL) models in cataclysmic variables and compare them with observed soft X-ray/extreme ultraviolet (EUV) spectra of dwarf novae in outburst.

Temperatture esttiimattiion off EXDRA and SSUMI dwarff Nova systtems from spectroscopic data
Iraqi Journal of Physics, 2019 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.

Dwarf nova outbursts with magnetorotational turbulence [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 The phenomenological Disc Instability Model has been successful in reproducing the observed light curves of dwarf nova outbursts by invoking an enhanced Shakura-Sunyaev $α$ parameter $\sim0.1-0.2$ in outburst compared to a low value $\sim0.01$ in quiescence.

Analysis of Three SU UMa-Type Dwarf Novae in the Kepler Field [PDF]
, 2013 We studied the Kepler light curves of three SU UMa-type dwarf novae. Both the background dwarf nova of KIC 4378554 and V516 Lyr showed a combination of precursor-main superoutburst, during which superhumps always developed on the fading branch of the ...

WZ Sge-type dwarf novae with multiple rebrightenings: MASTER OT J211258.65+242145.4 and MASTER OT J203749.39+552210.3 [PDF]
, 2013 We report on photometric observations of two WZ Sge-type dwarf novae, MASTER OT J211258.65+242145.4 and MASTER OT J203749.39+552210.3, which underwent outbursts in 2012. Early superhumps were recorded in both systems.

Outburst Photometry of the Eclipsing Dwarf Nova GY Cancri
, 2002 We observed the ROSAT-selected eclipsing dwarf nova GY Cnc (=RX J0909.8+1849) during the 2001 November outburst. We refined the orbital period to be 0.17544251(5) d.

, 2009 We report the observation of a new dwarf nova, OT J055717+683226, during its first-ever recorded superoutburst in December 2006. Our observation shows that this object is an SU UMa-type dwarf nova having a very short superhump period of 76.67+/- 0.03 min

Relation between Long-term Activity and Luminosity of the Pre- and Post-novae CT Ser and V446 Her
The Astronomical Journal, 2023 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.
