Abstract : Using the data from observation made with XMM-Newton, we present temporal and spectral analysis of an intermediate polar-like object Paloma. From the X-ray data, we report two persistent periods at 156±6 min and 130±4 min, which we interpreted as orbital and spin periods. We also interpreted Paloma is a key object for magnetic CV evolution with an orbital period right within the period gap. The averaged spectral data obtained from the XMM-Newton European Photon Imaging Camera is composed with an optically thin plasma emission components at 0.09 keV and 12.5 keV, which is strongly absorbed by dense material with an equivalent hydrogen column density of 6.1×10^22 cm-2 partially covering 64% the X-ray source together with one Gaussian at 6.4 keV Fe emission line. We also present the orbital and spin phase-resolved spectroscopy for Paloma in 0.3-10.0 keV energy range.
