More on the nature of the variable star UNSW-V-760.

KOEN C.

Abstract (from CDS):

The results of two multicolour time-series photometric observing runs, separated by about two months, are presented. The same periodicities previously detected in photometry of UNSW-V-760 are still present, albeit at substantially reduced amplitudes. Amplitudes also changed considerably between the two runs. A new periodicity, probably the second harmonic of one of the modes, has appeared. Flares were observed in one of the observing runs. All Sky Automated Survey photometry of the star shows overt variability over a limited time-span. The possibility is entertained that the properties can be explained by chance alignment of the K dwarf star with a distant blue pulsator.
