Timing Analysis of the Intermediate Polar V709 Cas

TL;DR

This paper presents detailed timing analysis of the intermediate polar V709 Cas using TESS data, confirming known periods and revealing it as a disc overflow system with disc-fed dominance.

Contribution

The study provides precise measurements of orbital, spin, and beat periods of V709 Cas and characterizes its accretion mode using high-cadence optical photometry.

Findings

Orbital period of 5.3341 hours

Spin period of 312.75 seconds

Disc overflow system with disc-fed dominance

Abstract

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. We found an orbital period of 5.3341 $\pm$ 0.0004 hr, a spin period of 312.75 $\pm$ 0.02 sec, and a beat period of 317.93 $\pm$ 0.03 sec, which is similar to the earlier published results. From the continuous high cadence data, we found that V709 Cas is a disc overflow system with disc-fed dominance.
