On the spin modulated circular polarization from the intermediate polars NY Lup and IGRJ1509-6649
Stephen B. Potter, Encarni Romero-Colmenero, Marissa Kotze +4
We report on high time resolution, high signal/noise, photo-polarimetry of the intermediate polars NY Lup and IGRJ1509-6649. Our observations confirm the detection and colour depen…
Characterizing X-ray binary long-term variability
M. M. Kotze, P. A. Charles
Long-term ("superorbital") periods or modulations have been detected in a wide variety of both low and high-mass X-ray binaries at X-ray and optical wavelengths. A variety of mecha…
Possible detection of two giant extrasolar planets orbiting the eclipsing polar UZ Fornacis
Stephen B. Potter, Encarni Romero--Colmenero, Gavin Ramsay +11
We present new high-speed, multi-observatory, multi-instrument photometry of the eclipsing polar UZ For in order to measure precise mid-eclipse times with the aim of detecting any…
