Evolution of Hydromagnetic Disturbances in Low Ionized Cosmic Plasmas
We consider the propagation of hydromagnetic waves generated by a compact turbulent source in low ionized plasmas, applying the Lighthill theory. We assume the plasma to be isothermal, and adopt a uniform, stationary medium thread by ordered magnetic fields as an initial condition. Then, the distinct properties of the hydromagnetic waves originating from a source oscillating with a fixed freque...
متن کاملThe Structure of Hydromagnetic Shock Waves
Es werden Wellen in einem quasi-neutralen Gas untersucht, das Ionen und Elektronen enthält und genügend kalt ist, so daß die thermischen Bewegungen vernachlässigt werden können. Außerdem werden Zusammenstöße zwischen den Teilchen vernachlässigt, jedoch nicht die Trägheitseffekte des elektrischen Stromes. Die nicht-linearen Gleichungen für unendlich ausgedehnte, ebene Kompressionswellen, die sic...
متن کاملThermodynamic properties of the ionized gas 3He
In this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3He atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. To perform the calculations, we have considered the kinetic term, and Coulomb interaction between the particles in our Hamiltonian. The calculated properties are free ener...
متن کاملRadiative feedback from ionized gas
H2 formation in metal-free gas occurs via the intermediate H − or H+2 ions. Destruction of these ions by photodissociation therefore serves to suppress H2 formation. In this paper, I highlight the fact that several processes that occur in ionized primordial gas produce photons energetic enough to photodissociate H− or H+2 and outline how to compute the photodissociation rates produced by a part...
متن کاملIonized Gas in the Smith Cloud
We present Wisconsin Hα Mapper observations of ionized gas in the Smith Cloud, a high velocity cloud which Lockman et al. have recently suggested is interacting with the Galactic disk. Our Hα map shows the brightest Hα emission, 0.43± 0.04 R, coincident with the brightest H I, while slightly fainter Hα emission (0.25 ± 0.02 R) is observed in a region with H I intensities < 0.1 times as bright a...
