Scientific paper

We propose to observe the Narrow Line Seyfert 1 galaxy IRAS~13349+2438 with XMM--Newton for a total exposure of 130~ks. The main objective of our proposal are 1) the study of the Fe K band which exhibits spectral complexity due to the simultaneous presence of a broad relativistic Fe line and absorption structures, one of which is significantly redshifted with respect to the expected energy. We will use the observation to separate the different spectral components, to confirm the presence of energy--shifted absorption lines, and to study the short timescale variability of the absorption features; 2) the study of the warm absorber and, in particular, of its long--term variations.
