N2 - 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 general relativity and the effects of Newtonian physics that are associated to oblateness of the compact star. The Keplerian frequency at this orbit may increase as well as decrease when the compact star angular momentum increases. In this context we explore behaviour of the ISCO frequency for compact star models calculated within the Hartle-Thorne spacetime approximation.
