Neutron stars with a weak magnetic field (up to 10^9 G) show various phenomena: pulsations, bursts, quasi-periodic oscillations (QPOs), and more. Each of them has been extensively studied in the last years using spectroscopic, timing, and polarimetric analyses, and each of them holds unique information regarding the structure, evolution, and emission mechanisms of neutron stars. In the session, we intend to bring together experts in various analyses to discuss the most recent advances in the studies of weakly magnetized neutron stars.

We intend to dedicate one block to the accreting millisecond pulsars, one of which has been recently observed in X-ray polarimetry for the first time. The second block will be about the rotation-powered millisecond pulsars which allowed, by modeling NICER pulse profiles in three of them, to obtain constraints on the EoS and field geometry. The last block will be dedicated to the non-pulsating weakly magnetized neutron stars and updates on their geometry obtained with polarimetry, and on their bursts and QPOs with timing analysis. With all these results presented together, we aim to search for trends, patterns, and directions for future joint research.
