Description
In the vicinity of the black hole where the gravitational and
electromagnetic fields play important role, relativistic
magnetohydrodynamics (GRMHD) should be used as a good model for the accreting plasma. There is a formal equivalence between GRMHD equations and equations for dynamics of relativistic string: the current-carrying string loops could represent plasma exhibiting a string-like behavior due to dynamics of the magnetic field lines, or due to the thin flux tubes of magnetized plasma can be simply described as 1D strings. Unfortunately, circular configuration located around central gravitational attractor (star or compact object) is unstable against some vibrational modes, see example in Larry Niven
book Ringworld. In this presentation I would like to show our outgoing research on string loop model dynamics, its stability and vibrational modes.
