Abstract (from CDS):

We present the analysis of a 100ks INTEGRAL (3-100keV) observation of the transient X-ray pulsar V0332+53 in outburst. The source is pulsating at PPulse=4.3751±0.0002s with a clear double pulse from 6keV to 60keV . The average flux was ∼550mCrab between 20keV and 60keV . We modeled the broad band continuum from 5keV to 100keV with a power-law modified by an exponential cut off. We observe three cyclotron lines: the fundamental line at 24.9+0.1–0.1keV, the first harmonic at 50.5+0.1–0.1keV as well as the second harmonic at 71.7+0.7–0.8 keV, thus confirming the discovery of the harmonic lines by Coburn et al. (2005ATel..381....1C) in RXTE data.
