Discrete spectral features (emission/absorption lines, absorption edges, recombination continua) are observed in the entire electromagnetic spectral range from astrophysical objects. They carry information about physical conditions, elemental abundances and dynamics of astrophysical plasma. This course will cover physical processes leading to production of those spectral features, and methods of inferring the physical parameters from observational data. |
