The JCMT Gould Belt Survey: SCUBA-2 observations of radiative feedback
  in NGC1333
  We present observations of NGC1333 from SCUBA-2 on JCMT, observed as a JCMT
Gould Belt Survey pilot project during the shared risk campaign when the first
of four arrays was installed at each of 450 and 850 microns. Temperature maps
are derived from 450 micron and 850 micron ratios under the assumption of
constant dust opacity spectral index beta=1.8. Temperatures indicate that the
dust in the northern (IRAS 6/8) region of NGC1333 is hot, 20-40 K, due to
heating by the B star SVS3, other young stars in the IR/optically visible
cluster, and embedded protostars. Other luminous protostars are also identified
by temperature rises at the 17" resolution of the ratio maps (0.02 pc assuming
a distance of 250 pc for Perseus). The extensive heating raises the possibility
that the radiative feedback may lead to increased masses for the next
generation of stars.
