Investigating the low-flux states in six Intermediate Polars
Ava E. Covington, Aarran W. Shaw, Koji Mukai +30
We present optical photometry of six intermediate polars that exhibit transitions to a low-flux state. For four of these systems, DW Cnc, V515 And, V1223 Sgr and RX J2133.7+5107, w…

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…
