Turbulent velocity structure in interstellar clouds
J. M. Scalo;
ApJ, 1984, 277, 556
ABSTRACT:A number of observed phenomena suggest that cloud internal velocity fields possess a disordered, or 'turbulent',
component.
In such a case, an important characterization of the velocity field would
be its spatial correlation structure.
The disordered velocity field in
clouds has recently been interpreted on the basis of an empirical relation
between spectral linewidth and scale size.
The present investigation is
concerned with a more direct method for the determination of the turbulent
velocity structure using well-sampled observations of mean velocities, to
estimate the accuracy with which mean velocities must be measured for this
objective.
