INTEGRAL OBSERVATION OF THE ACCRETING PULSAR 1E1145.1-6141

We analyzed 1050 ks of INTEGRAL data regarding the X-ray binary pulsar 1E 1145-6141. We performed tim-ing analysis, finding a spin period of ∼ 297 s, and spec-tral analysis as a function of the source luminosity. We find that the source spectrum can be modeled using an ab-sorbed bremsstrahlung model in which the electron tem-perature is correlated with the luminosity while the height of the absorbing column is anti-correlated. We also find and discuss briefly a phase shift of the pulse profile peak with photon energy. 1
