A molecular line survey of Orion KL in the 350 micron band. (2005)

Keywords : ISM abundances - ISM: individual (Orion) - ISM: molecules - line: formation - line: identification - submillimeter

Abstract:With the Caltech Submillimeter Observatory, we have carried out an unbiased spectral line survey of Orion KL throughout the 350{mu}m band (from 795 to 903GHz). This is the first systematic study of molecular radiation in this frequency range. A total of 541 features, resulting from 929 transitions from a total of 26 species, have been detected. High-excitation transitions from CH_3_OH, CH_3_CN, H_2_CO, HNCO, and C_2_H_5_CN indicate the presence of a very hot (~250K) component at the systemic velocity characteristic of the Hot Core. Physical parameters (column density and rotational temperature) relative to a number of species have been estimated by fitting, in the LTE (Local Thermodynamic Equilibrium) approximation, the whole 100GHz spectrum at ...(more)
