The Spin-Period History of Intermediate Polars
Joseph Patterson, Enrique de Miguel, Jonathan Kemp +25
We report the detailed history of spin-period changes in five intermediate polars (DQ Herculis, AO Piscium, FO Aquarii, V1223 Sagittarii, and BG Canis Minoris) during the 30-60 yea…
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…
A 16-Year Photometric Campaign on the Eclipsing Novalike Variable DW Ursae Majoris
D. R. S. Boyd, E. de Miguel, J. Patterson +29
We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previousl…
The asynchronous polar V1432 Aquilae and its path back to synchronism
David Boyd, Joseph Patterson, William Allen +23
V1432 Aquilae is the only known eclipsing asynchronous polar. In this respect it is unique and therefore merits our attention. We report the results of a 15-year campaign by the gl…
BK Lyncis: The Oldest Old Nova?... And a Bellwether for Cataclysmic-Variable Evolution
Joseph Patterson, Helena Uthas, Jonathan Kemp +21
We summarize the results of a 20-year campaign to study the light curves of BK Lyncis, a nova-like star strangely located below the 2-3 hour orbital period gap in the family of cat…
Superoutbursts of the SU UMa-type dwarf nova CP Draconis
Jeremy Shears, David Boyd, Denis Buczynski +8
Analysis of observations of the SU UMa-type dwarf nova, CP Dra, between February 2001 and April 2009 has revealed 15 outbursts, at least eight of which were superoutbursts. The sup…
