A Surprising Periodicity Detected during a Super-outburst of V844 Herculis by TESS
We identify a previously undetected periodicity at a frequency of 49.08 ± 0.01 days ^−1 (period of 29.34 ± 0.01 minutes) during a super-outburst of V844 Her observed by TESS. V844 Her is an SU UMa type cataclysmic variable with an orbital period of 78.69 minutes, near the period minimum. The frequen...
