Scientific paper

Lightcurves of the cataclysmic variable V1159 Orionis have been analyzied to study the outbursts, superoutbursts, and superhumps in this SU Uma-type dwarf nova. The data are merged from RoboScope observations over 7 years plus 3 years of CCD measures from amateur astronomers. The outbursts occur at an interval of ~4 days, with superoutbursts each 44.5 days. At times we find superhumps at all superoutburst phases, as well as a double-peaked structure within the star's ~0.06 day oscillations. These oscillations are often damped during the peaks of the normal outbursts, and a general strengthening occurs during superoutburst, peaking near the end of the superoutburst. This work was done as part of a summer REU program at Indiana University.
