The Z CamPaign: Year 1
Mike Simonsen
The Cataclysmic Variable Section of the American Association of Variable Star Observers (AAVSO) has initiated an observing campaign to study a subset of dwarf novae (DNe), known as…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. II: The Second Year (2009-2010)
Taichi Kato, Hiroyuki Maehara, Makoto Uemura +56
As an extension of the project in Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 61 SU UMa-type dwarf novae mainly observed during the 2009-2010 se…
A Study of the Unusual Z Cam Systems IW Andromedae and V513 Cassiopeia
Paula Szkody, Meagan Albright, Albert P. Linnell +7
The Z Cam stars IW And and V513 Cas are unusual in having outbursts following their standstills in contrast to the usual Z Cam behavior of quiescence following standstills. In orde…
The Z CamPaign: Year Five
Mike Simonsen
Entering into the fifth year of the Z CamPaign, the author has developed a website summarizing our findings which will also act as a living catalog of bona fide Z Cam stars, suspec…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. IV: The Fourth Year (2011-2012)
Taichi Kato, Franz-Josef Hambsch, Hiroyuki Maehara +85
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we studied 86 SU UMa-type dwarf novae. We confirmed the general trends such as the relation between period…
Z Cam Stars in the Twenty-First Century
Mike Simonsen, David Boyd, Bill Goff +12
Z Cam stars are a small subset of dwarf novae that exhibit standstills in their light curves. Most modern literature and catalogs of cataclysmic variables quote the number of known…
