Sobre el tipo de metamorfismo regional progresvo hercínico en el Guadarrama oriental (Sistema central español)

Discusión sobre el tipo del metamorfismo regional progresivo hercínico del Guadarrama oriental. Se trata de un tipo intermedio de baja presión, con distena, muy parecido a los tipos que ya se conocen en Galicia, Portugal y Sur de la Península

Collisional and Radiative Processes in Optically Thin Plasmas

Most of our knowledge of the physical processes in distant plasmas is obtained through measurement of the radiation they produce. Here we provide an overview of the main collisional and radiative processes and examples of diagnostics relevant to the microphysical processes in the plasma. Many analyses assume a time-steady plasma with ion populations in equilibrium with the local temperature and Maxwellian distributions of particle velocities, but these assumptions are easily violated in many cases. We consider these departures from equilibrium and possible diagnostics in detail
