Real Fluids, temperature, chemical composition, etc.). If any of these quantities is not uniformly distributed, the system is not in equilibrium and exchanges occur of a mechanical or thermal nature between nearby elements until equilibrium is eventually achieved.

The Interstellar Medium,l conductivity there is no thermal contact with the surrounding medium and the dissipation of energy by viscosity is negligible. In general, viscosity and thermal conduction are also of little importance in interstellar gas. Consider the role of thermal conduction in a molecular cloud of size ., wit

Electrodynamics and Magnetohydrodynamics, electrons and on the ions producing currents. In turn currents cause alterations in the electro-magnetic field: hence, we have to do with a complicated coupled system of matter and fields. We focus on conductor fluids, that is, on ionised gases. The fundamental difference between a non-conducting g

Magnetohydrodynamic Waves, the magnetic tension tends to bring them back into rectilinear form, however causing transverse oscillations. This type of magnetohydrodynamic wave, called Alfven wave, is the only one possible in an incompressible fluid. If we assume infinite electrical conductivity, the magnetic lines of force ar

Stellar Winds, is called stellar wind. The existence of these winds was revealed mostly through the UV spectra obtained with the IUE satellite; the resonance lines of these spectra have P-Cygni profiles (see Fig. .). These profiles consist of an absorption component shifted to shorter wavelengths, and an emission

Star Formation,of formation of the two types of stars are spatially separated, more precisely there are regions where only low-mass stars are formed and regions where both low-mass and massive stars are formed. For example, the Taurus region does not seem to contain stars more massive than 2 ., while in Orion both
