In the field of the eruptive, EX-Ori type, variable Gaia19fct, we find the variable object IRAS 07063-1016 or 2MASS J07084063-1021246. We show the V, R, and I-band data we have collected in the plot above.
While there is a gap in the data and the light curve is not yet very long (only since the namesake of the field was identified in 2019), the object still shows some interesting behaviour. While its normal day to day brightness variations are quite small, of the order of a few percent, it quite often shows rapid (days) brightening or dimming events that are of the order of 30-50 percent of its flux, or 0.3-0.5mag.
These events don’t really seem to follow any particular trends. They also don’t seem to be in line with dipping or bursting events that one sometimes sees in young stellar light curves. The object is certainly unique amongst all the YSO light curves we have looked at so far. It hence represents one of those intriguing, individual objects that are worth having a close look … need to find some time 🙂
