The Dwarf Nova Outbursts of Nova Her 1960 (=V446 Her) [PDF]
The Astronomical Journal, 2011 V446 Her is the best example of an old nova which has developed dwarf nova eruptions in the post-nova state. We report on observed properties of the long-term light curve of V446 Her, using photometry over 19 years.

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova [PDF]
The Astrophysical Journal Letters, 2023 T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poorly studied thus far. Because of that their nature remained unknown.

Evolution of Negative Superhumps, Quasiperiodic Oscillations, and Outbursts in the Z Cam-type Dwarf Nova AH Her [PDF]
The Astrophysical Journal, 2023 AH Her is a Z Cam-type dwarf nova with an orbital period of ∼0.258 days. Dwarf nova oscillations and long-period dwarf nova oscillations have been detected, but no quasiperiodic oscillations (QPOs) and negative superhumps (NSHs) have been found.

Superoutburst of a New Sub-Period-Minimum Dwarf Nova CSS130418 in Hercules
Acta Polytechnica CTU Proceedings, 2015 Multicolour photometry of a new dwarf nova CSS130418 in Hercules, which underwent superoutburst on April 18, 2013, allow to classified it as a WZ Sge-type dwarf nova. The phase light curves for different stages of superoutburst are presented.

The Dwarf Nova PQ Andromedae [PDF]
Publications of the Astronomical Society of the Pacific, 2005 We report a photometric study of the WZ Sagittae-type dwarf nova PQ Andromedae. The light curve shows strong (0.05 mag full amplitude) signals with periods of 1263(1) and 634(1) s, and a likely double-humped signal with P=80.6(2) min.

A dwarf nova in the globular cluster M13 [PDF]
, 2011 Dwarf novae in globular clusters seem to be rare with only 13 detections in the 157 known Galactic globular clusters. We report the identification of a new dwarf nova in M13, the 14th dwarf nova identified in a globular cluster to date.

BO Ceti: Dwarf nova showing both IW And-type and SU UMa-Type features [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2021 IW And stars are a recently recognized subgroup of dwarf novae which are characterized by (often repetitive) slowly rising standstills terminated by brightening, but the exact mechanism for this variation is not yet identified.

Modelling rebrightenings, reflares, and echoes in dwarf nova outbursts [PDF]
Astronomy & Astrophysics, 2021 The disc instability model accounts well for most of the observed properties of dwarf novae and soft X-ray transients, but the rebrightenings, reflares, and echoes occurring at the end of outbursts or shortly after in WZ Sge stars or soft X-ray ...

First discovery of QPOs in the dwarf nova HS 2325+8205 based on TESS photometry [PDF]
, 2023 HS 2325+8205 is a long-period eclipsing dwarf nova with an orbital period above the period gap (Porb>3 h) and is reported to be a Z Cam-type dwarf nova. Based on the photometry of the Transiting Exoplanet Survey Satellite (TESS), the light variation and ...
