RXTE confirmation of the intermediate polar status of IGR J15094-6649.


Abstract (from CDS):

We aim to establish the X-ray properties of the intermediate polar candidate IGR J15094-6649 and therefore confirm its inclusion into the class. 42856 s of X-ray data from RXTE was analysed. Frequency analysis was used to constrain temporal variations and spectral analysis used to characterise the emission and absorption properties. A spin period of 809.7±0.6s is present, revealed as a complex pulse profile whose modulation depth decreases with increasing X-ray energy. The spectrum is well fitted by either a 17±4keV Bremsstrahlung or Γ=1.8±0.1 power law, with an iron emission line feature and significant absorption in each case. IGR J15094-6649 is confirmed to be an intermediate polar.
