Abstract (from CDS):

We intend to establish the X-ray properties of Swift J0732.5-1331 and therefore confirm its status as an intermediate polar. We analysed 36240s of X-ray data from RXTE. Frequency analysis was used to constrain temporal variations and spectral analysis used to characterise the emission and absorption properties. The X-ray spin period is confirmed to be 512.4(3)s with a strong first harmonic. No modulation is detected at the candidate orbital period of 5.6h, but a coherent modulation is present at the candidate 11.3h period. The spectrum is consistent with a 37keV bremsstrahlung continuum with an iron line at 6.4keV absorbed by an equivalent hydrogen column density of around 1022atoms/cm2. Swift J0732-1331 is confirmed to be an intermediate polar.
