1998 Superoutburst of the Large-Amplitude SU UMa-Type Dwarf Nova WX Ceti

, 2001
We observed the 1998 November superoutburst of WX Cet, a dwarf nova originally proposed as a WZ Sge-like system. The observation established that WX Cet is an SU UMa-type dwarf nova with a mean superhump period of 0.05949(1) d, which is 2.1% longer than ...

A Demarcation Criterion for Hydrogen Burning of Millinovae

The Astrophysical Journal
Millinovae are a new class of transient supersoft X-ray sources with no clear signature of mass ejection. They show similar triangle shapes of V / I band light curves with 1000 times fainter peaks than typical classical novae. Maccarone et al.

Series of Dwarf Nova Outbursts in the Post-novae AT Cancri and GK Persei

The Astronomical Journal
AT Cancri and GK Persei are post-novae (Nova Cnc in the seventeenth century and Nova Per 1901). Nowadays, they show episodic brightenings attributed to dwarf nova (DN) outbursts.

A Phenomenon Resembling Early Superhumps in a New SU UMa-type Dwarf Nova with a 2 hr Orbital Period

The Astronomical Journal
We investigate K2BS5, an optical transient that we identified in Campaign 13 of the Kepler/K2 archives by the K2 Background Survey, and classify it as a new SU UMa-type dwarf nova.

The AH Pictoris Syndrome: Continuous Trains of Stunted Outbursts in Novalike Variables

The Astrophysical Journal
Novalike variables are a subgroup of cataclysmic variables (CVs) that—unlike dwarf novae—do not exhibit strong brightenings in their long-term light curves.

Following the Pulsations in the Long-term Cooling of GW Librae and V386 Serpentis

The Astronomical Journal
GW Lib and V386 Ser are dwarf novae systems containing pulsating white dwarfs that underwent large 8–9 mag amplitude outbursts in 2007 and 2019, respectively.
