Description

We have carried detailed time-resolved timing analysis of an intermediate polar V709 Cas, using the long-baseline, short cadence optical photometric data from the Transiting Exoplanet Survey Satellite(TESS). We found an orbital period of $5.332965\pm 0.000007$ hr, a spin period of $312.7488\pm 0.0004$ sec and a beat period of $317.9265\pm 0.0004$ sec, which are similar and more precise than the earlier published results. From the continuous data, we report the system's accretion geometry as disc overflow with disc-fed dominance with some part of it being also stream-fed. The double peaked pulse profile nature shows it being a two pole accretor.
