Scientific paper

High resolution observations in 13CO and 12CO lines of a molecular cloud of low column density close to the Sun reveal that 85% of the 13CO emission arises in small discrete cells in (l,b,v) space. These cells trace very small scale density enhancements which are likely to be transient. The maxima of local density are several times larger than the average density on the line of sight, but are too low by two orders of magnitude to be bound by their self-gravity. These data show that molecular gas of moderate extinction may exhibit fine structure characterized by important density gradients at surprisingly small scales. This suggests that this gas component is effectively compressible with respect to the turbulent velocity field inside the cloud.
