Description

The Imaging X-ray Polarimetry Explorer (IXPE) is opening a new observational window into the physics of weakly magnetized neutron stars in low-mass X-ray binaries (LMXBs). In particular, coordinated multi-instrument campaigns have enabled the first systematic studies of the polarization signatures from bright Atoll-type sources. In this contribution, we focus on the source GX 9+1 and present recent spectro-polarimetric results, underlining the energy dependence of the polarization degree. We also compare these results with those obtained for other Atoll sources, discussing the emerging trends and their implications for the geometry and emission mechanisms in these systems.
