We present spectral and energy-dependent timing characteristics of the hard X-ray transient IGR J17497–2821 based on XMM–Newton observations performed five and nine days after its outburst on 2006 September 17. We find that the source spectra can be well described by a hard ( ∼ 1.50) power law and a weak multicolour disc blackbody with inner disc temperature kTin ∼ 0.2 keV. A broad iron Kα line with FWHM ∼ 27 000 km s−1, consistent with that arising from an accretion disc truncated at...[Show more]
