Multi-wavelength observations of the massive YSO RAFGL 7009S.

Abstract (from CDS):

We present multi-wavelength observations of the young stellar object RAFGL 7009S. The analysis combines single dish (IRAM 30m), interferometric (Plateau de Bure Interferometer), as well as infrared (UKIRT and ISO) observations. We use those data to globally describe the source (Spectral Energy Distribution, density) and its environment. We also derive the position of the central object (associated with the HII region) to 1'' precision using the interferometer observations. We have observed HDO and CH3OD in single dish measurements and derive the D/H ratio for water and methanol in the gas phase. Laboratory experiments allow us to derive upper limits to the enrichment of the same species in the solid phase. It is argued that CH3OH seems to be a good tracer for grain deuterium enrichment in the environment of RAFGL 7009S. Observations of HCN and HNC isomers indicate that along the line of sight, two velocity independent temperature regions coexist.
