Oscillating string loops in the field of compact object

Relativistic current-carrying string loops moving axisymmetrically along the symmetry axis of central object could in a simplified way represent plasma that exhibits associated string-like behaviour. We will discuss string loops dynamics in Schwarzschild, braneworld and Kerr black holes / naked singularities. The astrophysical applications have been focused on the problem of acceleration of string loops along symmetry axis (jet like motion) and on the small oscillations of string loops in vicinity of stable equilibrium positions (model of HF QPOs).
