Scientific paper

A gaseous accretion disk around a compact object is a promising model of galactic and extragalactic high-energy sources. In the present work, the Chandrasekhar-Friedmann trial function method is used to calculate the frequency of the axisymmetric oscillations of a non-self-gravitating perfect-fluid disk rotating around a compact object. The frequency appears to be about 1 kHz when m is about 1 km and the disk has a size of about 40 m.
