Abstract

Twin quasi-periodic oscillations have been observed in the emission spectrum of neutron star binaries. The models that have been proposed do not succeed to explain the frequency difference between the two kHz QPO, which is close but distinct from the rotation frequency of the neutron star. I will present a new model based on the dynamics of the gas trapped in the neutron star magnetosphere.
