Structure of a steady-state corona formed by irradiation of a cylindrical target

An analysis is made of the problem of the hydrodynamics of a steady-state corona formed by the action of powerful laser radiation on a cylindrical target. Universal dependences describing this process are presented in the form of graphs and asymptotic expansions. At sufficiently low radiation intensities the critical point coincides with the isothermal Jouguet point, whereas the adiabatic Jouguet point is located elsewhere.
