An Improved Estimate of the Mass of Dust in Cassiopeia A
  Recent observations of sub-millimeter continuum emission toward supernova remnants (SNR) have raised the question of whether such emission is caused by dust within the SNR and thus produced by the supernova itself or along the line-of-sight. The importance of the present work is to establish evidence for the production of large amounts of dust in supernovae. The best tests can be made for young supernovae in our galaxy. Cassiopeia A is the best candidate for a measurement.
