Restricted Access. An open-access version is available at arXiv.org (one of the alternative locations)We report the timing and broad-band spectral properties of the Be transient high-mass X-ray binary pulsar GRO J1008−57 using a Suzaku observation in the declining phase of its 2007 November and December outbursts. Pulsations with a period of 93.737 s were clearly detected in the light curves of the pulsar up to the 80–100 keV energy band. The pulse profile was found to be strongly energy dependent, a double-peaked profile at soft X-ray energy bands (<8 keV) and a single-peaked smooth profile at hard X-rays. The broad-band energy spectrum of the pulsar, reported for the first instance in this paper, is well described with three different con...
