Two-component radiation model of the sonoluminescing bubble

Based on the experimental data from Weninger, Putterman & Barber, Phys. Rev. (E), 54, R2205 (1996), we offer an alternative interpretation of their experimetal results. A model of sonoluminescing bubble which proposes that the electromagnetic radiation originates from two sources: the isotropic black body or bramsstrahlung emitting core and dipole radiation-emitting shell of accelerated electrons driven by the liquid-bubble interface is outlined.

On the conical refraction of hydromagnetic waves in plasma with anisotropic thermal pressure: general consideration

A phenomenon analogous to the conical refraction well-known in the crystalooptics and crystaloacoustics is considered for the magnetohydrodynamical waves in a collisionless plasma with anisotropic thermal pressure. Imposing the most general (generalization of Tsiklauri, 1996, Phys. Plasmas, 3, 800) condition for the existence of the phenomenon, angle of the conical refraction is calculated which appeared to be dependent on the ratio of the Alfven velocity and sound speed measured in the perpendicular direction in respect to the external magnetic field. Feasible ways of experimental demonstration of the phenomenon are discussed and a novelty brought by the general consideration is outlined.

On the conical refraction of hydromagnetic waves in plasma with anisotropic thermal pressure

A phenomenon analogous to the conical refraction widely known in the crystalooptics and crystaloacoustics is discovered for the magnetohydrodynamical waves in the collisionless plasma with anisotropic thermal pressure. Angle of the conical refraction is calculated for the medium under study which is predicted to be $18^{\circ}26^{\prime}$. Possible experimental corroborating of the discovered phenomenon is discussed.
