Spectral signature of oscillating slender accretion tori

I will investigate a model of microquasar high-frequency QPOs that assumes these oscillations are due to an oscillating slender torus. I will show power spectral densities ray-traced in the Kerr metric and discuss the predictions of this model as well as perspectives of comparison to data.
