Investigating the physical properties and fragmentation of the AFGL
  333-Ridge
  We present multi-wavelength data to investigate the physical properties and
fragmentation of AFGL 333- Ridge. A statistical analysis of velocity dispersion
indicates that turbulence is the dominant motion in the ridge. However, the
linear mass density (1124.0 M/pc) of AFGL 333-Ridge far exceeds its critical
value of 406.5 M/pc, suggesting that additional motions are required to prevent
the filament radial collapse. Using the getsources algorithm, we identified 14
cores from the Herschel maps, including two protostellar cores and 12 starless
cores. All of these starless cores are gravitationally bound, and are therefore
considered to be prestellar cores. Based on their radius-mass relation, 11 of
14 cores have the potential to form massive stars. Moreover, the seven cores in
two sub-filaments of AFGL 333-Ridge seem to constitute two necklace-like chains
with a spacing length of 0.51 pc and 0.45 pc, respectively. Compared the
spacing length with theoretical prediction lengths by Jeans and cylindrical
fragmentations, we argued that the combination of turbulence and thermal
pressure may lead to the fragmentation of the two sub-filaments into the cores.
