It has been suggested that observations of quasi periodic oscillations (QPOs) in the X-ray fluxes from low mass X-ray binaries can be used to constrain the mass of the compact object and the equation of state of its matter. A specific suggestion that the kHz QPO frequency saturates at the maximum orbital frequency has been widely considered. We examine rotating compact stars described by a new model of strange quark matter (Dey et al. 1998). We calculate the maximum orbital frequencies for both…

Innermost Stable Circular Orbits Around Rotating Compact Stars
Orbital motion close to a rotating compact star is largely affected by strong gravity. Location of the innermost stable circular orbit (ISCO) is determined trough interplay between the effects of
