ABSTRACT: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.
