Abstract (from CDS):

We present a preliminary analysis of the small-scale structure found in new 70-520 µm continuum maps of the Rosette molecular cloud (RMC), obtained with the SPIRE and PACS instruments of the Herschel Space Observatory. We find 473 clumps within the RMC using a new structure identification algorithm, with sizes up to ∼1.0pc in diameter. A comparison with recent Spitzer maps reveals that 371 clumps are ``starless'' (without an associated young stellar object), while 102 are ``protostellar.'' Using the respective values of dust temperature, we determine the clumps have masses (MC) over the range -0.75≤log(MC/M☉)≤2.50. Linear fits to the high-mass tails of the resulting clump mass spectra (CMS) have slopes that are consistent with those found for high-mass clumps identified in CO emission by other groups.
