## Abstract

The innermost stable circular orbit (ISCO) of a test particle around a Schwarzschild black hole of mass M is located at r_ isco=6M G/c^2 (Schwarzschild coordinate radius). If the particle is endowed with mass ?(\ll M), it experiences a gravitational self-force whose conservative piece alters the location of the ISCO. Here we calculate the resulting shifts ? r_ isco and ??_ isco in the ISCO's radius and frequency, at leading order in the mass ratio ?/M. We obtain ? r_ isco=-3.27 ? G/c^2 (in the Lorenz gauge) and ??_ isco/?_ isco=0.487 ?/M (gauge invariant). We discuss the implications of our result within the context of extreme mass-ratio binary inspirals.
