X-ray Beat Pulses of AO Psc
The energy-resolved X-ray beat pulses of
AO Psc.
Data are from the 1994 June ASCA observation
folded on the ephemeris of Kaluzny
& Semenuk 1988. The energy dependence suggests that the X-ray beat
pulses are not due to stream overflow accretion. It may be obscuration
modulated on the beat period, or possibly soft X-rays emitted from
photoionized plasma fixed in the orbital frame (e.g., the hot spot).
Since the observation covers 245 spin cycles and 16 orbital cycles pretty
uniformly, these beat pulses are probably not due to sampling effects.
