Abstract

GT Mus is a quadruple system containing an RS CVn-type binary and a pair of eclipsing A dwarfs. More than four years of continuous BV(RI)c photometry of the system has revealed spot-wave variability in the active component of the RS CVn binary. The amplitude and mean level of this spot wave change with time in an activity cycle. An infrared excess was also observed from time to time and this has been interpreted as hydrogen emission from flare events. The system is therefore remarkable for showing four different types of variability, all on different time-scales, and three of these associated with the active star.
