Investigating the low amplitude outbursts of long-orbital period CVs

Dwarf novae (DNe) outbursts of cataclysmic variables (CVs) typically have asymmetrical outburst profiles, lasting only a week or two. However, we note that long-orbital period DNe have a tendency to exhibit symmetrical light curve (SLC) outbursts with low amplitudes that last for weeks to months. It is not uncommon for DNe to exhibit low amplitude outbursts, however, long durations that can be on the timescale of nova eruptions are what makes them unique and of particular interest. We report on a study to investigate the variety of system properties that can produce SLC outbursts in long-$P_{\rm orb}$ CVs. We confirm V5760 Sgr as a long-$P_{\rm orb}$ DN based on its quiescent light curve and a low amplitude SLC outburst comparable with similar CVs, e.g. GK Per and V1017 Sgr. The donor of V5760 Sgr was also estimated to be a $\sim$G-IV star, based on our detection of a magnetic cycle of $\sim 11$ years.
