Structure function scaling of a 2MASS extinction map of Taurus.

PADOAN P., CAMBRESY L. and LANGER W.

Abstract (from CDS):

We compute the structure function scaling of a 2MASS extinction map of the Taurus molecular cloud complex. The scaling exponents of the structure functions of the extinction map follow Boldyrev's velocity structure function scaling of supersonic turbulence. This confirms our previous result based on a spectral map of 13CO J=1-0 covering the same region and suggests that supersonic turbulence is important in the fragmentation of this star-forming cloud.
