    • A centimetre-wave excess over free–free emission in planetary nebulae 

      Nyman, L. -A.; Dickinson, C.; Casassus Montero, Simón; Pearson, T. J. (WILEY-BLACKWELL, 2007-12-21)
      We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
