OBSERVATION OF 13CO AND METHANOL LINE EMISSION FROM SUPERNOVA REMNANT KES 79

摘要

Molecular environment of galactic supernova remnant Kes 79 is investigated using results of observations of ~(13)CO and methanol molecular line emission. The ~(13)CO emission line broadening associated with radial velocities about +90 and +105 km/s has been fìrst revealed. The effect suggests new evidence of the possible interaction of Supernova remnant Kes 79 with molecular clouds. The line broadening at the radial velocity +105 km/s was observed throughout the remnant surface, while that at +90 km/s was seen near its north-eastern boundary. A methanol maser has been detected in the direction of the OH-molecule emission region observed earlier in Kes 79. It is expected that the maser emission is a result of the Supernova remnant interaction with a molecular cloud moving at the radial υelocìty +90 km/s. The intensity of the detected source is variable with time.
