Orbital Period Changes in WZ Sagittae
Joseph Patterson, Geoffrey Stone, Jonathan Kemp +19
We report a long-term (1961-2017) study of the eclipse times in the dwarf nova WZ Sagittae, in an effort to learn its rate of orbital-period change. Some wiggles with a time scale…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
OT J002656.6+284933 (CSS101212:002657+284933): An SU UMa-Type Dwarf Nova with Longest Superhump Period
Taichi Kato, Tamas Tordai, Colin Littlefield +17
We observed the 2016 outburst of OT J002656.6+284933 (CSS101212:002657+284933) and found that it has the longest recorded [0.13225(1) d in average] superhumps among SU UMa-type dwa…
Resynchronization of the Asynchronous Polar CD Ind
G. Myers, J. Patterson, E. de Miguel +6
CD Ind is one of only four confirmed asynchronous polars (APs). APs are strongly magnetic cataclysmic variables of the AM Herculis subclass with the characteristic that their white…
