This paper studies the influence of turbulence generated by the supersonic motion of fragments formed during the collapse of a self-gravitating cloud. The dependence of the results upon the physical parameters needed to describe turbulence is investigated. The results are given for the three values of the gas cloud mass. The presence of turbulence with consequent dissipation is shown to raise appreciably the gas temperature. The results show that the turbulent velocity dispersion is sistematically smaller than the fragments' orbital velocity dispersion.

Abstract
This paper studies the influence of turbulence generated by the supersonic motion of fragments formed during the collapse of a self-gravitating cloud. The dependence of the results upon the physical parameters needed to describe turbulence is investigated. The results are given for the three values of the gas cloud mass. The presence of turbulence with consequent dissipation is shown to raise appreciably the gas temperature. The results show that the turbulent velocity dispersion is sistematically smaller than the fragments' orbital velocity dispersion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
