Abstract

We propose a unified version of hoop conjecture valid for various black holes and horizonless compact stars. This conjecture is expressed by the mass to circumference ratio 4πMin/C14\pi M_{in}/C\leqslant 1, where C is the circumference of the smallest ring that can engulf the object in all azimuthal directions and MinM_{in} is the mass within the engulfing sphere.
