A methanol line survey toward high-mass star-forming regions.


Abstract (from CDS):

We present the results of a search for methanol maser and thermal lines in 11 transitions in the range 85-112GHz toward 23 star-forming regions exhibiting class I and class II methanol masers. The selected frequencies are 85.5, 86.6, 94.5, 95.1, 96.7 (quartet line series), 107.0, 108.8 and 111.2GHz. Five masers were confirmed at 107.0GHz while new masers were found at 85.5, 86.6 and 108.8GHz. Many detected emission lines have a quasi-thermal origin. The detection rates of methanol emission are high at 95.1GHz (87%) and 96.7GHz (96%), satisfactory at 107.0 and 108.9GHz (∼50%) while the detection rates at 85.5, 94.5 and 111.3GHz are low (∼20%). Most reported 95.1GHz emission is masing.
