Introducing the Condor Array Telescope: III. The expansion and age of the shell of the dwarf nova Z Camelopardalis, and detection of a second, larger shell [PDF]
, 2023 The existence of a vast nova shell surrounding the prototypical dwarf nova Z Camelopardalis (Z Cam) proves that some old novae undergo metamorphosis to appear as dwarf novae thousands of years after a nova eruption.

Modelling hystereses observed during dwarf nova outbursts [PDF]
Astronomy & Astrophysics, 2020 Context. Although the disc instability model is widely accepted as the explanation for dwarf nova outbursts, it is still necessary to compare its predictions to observations because many of the constraints on angular momentum transport in accretion discs

First detection of two superoutbursts during the rebrightening phase of a WZ Sge-type dwarf nova: TCP J21040470+4631129 [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2020 We report on photometric and spectroscopic observations and analysis of the 2019 superoutburst of TCP J21040470+4631129. This object showed a 9 mag superoutburst with early superhumps and ordinary superhumps, which are the features of WZ Sge-type dwarf

Spectroscopic properties of the dwarf nova-type cataclysmic variables observed by LAMOST [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2020 Spectra of 76 known dwarf novae from the LAMOST survey were presented. Most of the objects were observed in quiescence, and about 16 systems have typical outburst spectra. 36 of these systems were observed by SDSS, and most of their spectra are similar

Discovery of standstills in the SU UMa-type dwarf nova NY Serpentis [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2019 We found that the SU UMa-type dwarf nova NY Ser in the period gap [orbital period 0.097558(6) d] showed standstills twice in 2018. This is the first clear demonstration of a standstill occurring between superoutbursts of an SU UMa-type dwarf nova.

ASASSN-14ho: Longest-period dwarf nova with multiple rebrightenings [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2019 The post-outburst rebrightening phenomenon in dwarf novae and X-ray novae is still one of the most challenging subjects for theories of accretion disks.

Gravity Modes on Rapidly Rotating Accreting White Dwarfs and Their Variation after Dwarf Novae
The Astrophysical Journal, 2023 Accreting white dwarfs (WDs) in cataclysmic variables (CVs) show short-period (tens of minutes) brightness variations that are consistent with nonradial oscillations similar to gravity ( g ) modes observed in isolated WDs.

International Astronomical Union Colloquium, 1995 AbstractThis report provides a summary of flares observed visually in the dwarf novae V442 Cen, OY Car, TU Men and Z Cha. The flares precede an outburst by an average of around ten days.
