We present the hard X-ray time-averaged spectrum of the intermediate polar V709 Cas observed with INTEGRAL. We performed the observation using data from the IBIS/ISGRI instrument in the 20–100 keV energy band and from JEM-X at lower energy (5–20 keV). Using different multi-temperature and density X-ray post-shock models we measured an improved post-shock temperature of ~40 keV and estimated the V709 Cas mass to be 0.82 . We compare the resulting spectral parameters with previously reported BeppoSAX and RXTE observations.
Key words: binaries: general / stars: individual: V709 Cas / X–rays: stars
