We present a spectral and temporal analysis of the accreting X-ray pulsar 4U 1909+07 observed with INTEGRAL and RXTE. Although this source is known already for many years, until recently only very little was known about it. 4U 1909+07 was only a few years ago discovered to be an accreting X-ray pulsar, although it is typically detected at a level of about 15 mCrab in INTEGRAL/ISGRI, but can reach about 300 mCrab during flaring activity. We perform one of the first detailed spectral and temporal analyzes of this source, i.e. we study the evolution of the pulse period, analyze the energy dependence of the pulse profile, model the broad band continuum, search for cyclotron resonant scattering features, and perform phase resolved spectroscopy.
