Plasma DiagnosticsPlasma with temperatures above a million Kelvin is common in the Universe. It exists, for the most part, in intergalactic space, but is also found in a variety of sources which range from optically thin (solar and stellar coronae, clusters of galaxies, supernova remnants, the tenuous intergalactic and interstellar space) to optically thick (accretion powered sources such as compact X-ray binaries, cataclysmic variables, and AGNs, where a central X-ray emitting region is surrounded by a cooler medium that is partially photo-ionized). X-ray spectral modelling is an important tool to study the physical parameters of such hot plasmas. [Ref 10] |
