Scientific paper

Far-infrared IRAS measurements of 46 of the brighter planetary nebulae are presented. Dust temperatures are computed. Higher dust temperatures are found in the younger, denser nebulae. Lyman α is shown to be a sufficient source of energy to heat the dust for the larger, older nebulae, but another energy source (probably the exciting star) is required for the younger nebulae.
