Non-Axisymmetric Modes in Relativistic Singular Isothermal Disks
Abstract
The relativistic singular isothermal disk equilibriumsolutions are self-similar and form a two-parameter family described by the sound speed and the linear rotational velocity. Using the equilibrium model as the base state, we study its stability against self-similar but non-axisymmetric perturbations. We discovered that instability can be manifested through radiation driven neutral modes and bifurcation points to non-axisymmetric equilibria.
