We investigate the role of the tidal charge in orbital models of
high-frequency quasiperiodic oscillations (QPOs) observed in neutron
star binary systems. We show how the standard relativistic precession
(RP) model modified by the tidal charge fits the observational data,
giving estimates of the allowed values of the tidal charge and the brane
tension based on the processes going in the vicinity of neutron stars.
We compare our strong field regime restrictions with those given in the
weak field limit of solar system experiments.
