Abstract:
Two telescopes are used at the Morgan-Monroe Observatory of Indiana
University for autonomous long-term photometric monitoring of stellar
sources, mostly cataclysmic variable stars. The instrumentation is
designed and implemented to be appropriate for multiyear automated
monitoring. The capabilities and limitations of the equipment are
described, along with accounts of the software, the reduction
procedures, the motivations for the scientific programs, and the
execution of the observing campaigns. Data on the AM CVn-type
cataclysmic variable CR Boo are presented and discussed as an example
of the kinds of light curves generated at this facility. The He-rich
disk in CR Boo has SU UMa-type outburst behavior, with both
superoutbursts and what appear to be dwarf nova outbursts. However,
the light curve is quite irregular and displays a wide variety of
unusual features such as switching among several superoutburst
recurrence intervals, and having intervals of dwarf nova-like
outbursts that seem to come and go. We discuss the likelihood that
deterministic chaos is responsible for these irregularities.
