[19.03] A Photometric Study of the Low States of AM Her

J. W. Robertson (Arkansas Tech University), S. Kafka, R. K. Honeycutt (Indiana University), S. B. Howell (WIYN/NOAO)

We present a photometric study of the low states of AM Her. Long-term (RoboScope) and continuous monitoring reveal flaring events with amplitudes of 0.2-0.6 magnitude and durations of 15-90 minutes. These events, which appear to be frequent during the latest low state (2004 February - present), can be due to either residual accretion or activity (flares) on the secondary star. The advantages and drawbacks of both mechanisms are discussed in terms of what is known about the magnetic accretion geometry and low-state behavior of AM Her.
