Scientific paper

There is no clear observational evidence for the contracting phase that should characterize star formation. In this paper the authors calculate, analytically, the expected CO wing line emission profile from a 1 M_sun; contracting protostellar fragment. The wings have a power law dependence with radial velocity with an index of -3, and the blue wing is about two times stronger than the red wing. This characteristic asymmetric profile can be detected after integration times of tens of hours with the new large radio telescopes for the millimeter waves (Nobeyama and Pico Veleta). Detection of this spectral "hallmark" may provide the observational confirmation of the contracting phase in star formation.
