Infrared Line Radiation from the Neighbourhood of the Galactic Center
Abstract
Calculations are made on the amount of line radiation in the infrared (between 2Oit and 200it) to be expected from the "thermal" regions in the neighbourhood of the galactic center. A comparison is made with the observed radiation in this wavelength region. Although the predicted line radiation is an order of magnitude lower than the observed radiation, the predicted flux depends on the assumed abundances, which may be higher than the solar values used. Th any case, at least 10 lines are expected to be present in observable strength, and observation of these lines can provide an accurate determination of the abundances of five elements at the galactic center. Key words: galactic center - interstellar matter - thermal radio emission - infrared line radiation
