Protostars: Methods Of Observation

Scientific paper

The authors present molecular-line observations of young stellar objects (YSOs) suspected to be protostars in the main accretion phase. The aim of this work is to define a list of the best protostellar candidates to be observed in the near future with the ISO spectrometers with the precise scope of searching for the final proof of the infall. The sources were mapped in the CS 3→2 and CO 3→2 lines; the data were used to investigate the presence of clumps of materials around these objects and the amount of this material, as well as to detect outflows associated with these objects that would enormously complicate the interpretation of further dynamics studies. Only one of the sources suspected to be protostars resulted to have a good chance of being in the accretion phase and to deserve further spectroscopic measurements.
