Query: Towards modeling quasi-periodic oscillations of microquasars with
  oscillating slender tori   Context. One of the often discussed models for X-ray binaries high-frequency
quasi-periodic oscillations is the oscillating torus model that considers
oscillation modes of slender accretion tori. Aims. Here, we aim at developing
this model by considering the observable signature of an optically thick
slender accretion torus subject to simple periodic deformations. Methods. We
compute light curves and power spectra of a slender accretion torus subject to
simple periodic deformations: vertical or radial translation, rotation,
expansion and shear. Results. We show that different types of deformations lead
to very different Fourier power spectra and therefore could be observationally
distinguished. Conclusions. This work is a first step in a longer-term study of
the observable characteristics of the oscillating torus model. It gives
promising perspectives on the possibility to constrain this model by studying
the observed power spectra of quasi-periodic oscillations.
