Global simulations of accretion onto weakly magnetized neutron stars: variability and strong gravity

We show the results of new global 3D simulations of disc accretion onto a weakly magnetized neutron star.
We analyze different frequencies, including possible very high-frequency QPOs excited around stars of
different masses, and discuss the applicability of these results to the measure of NS masses through
observations with large effective-area satellites like LOFT
