Scientific paper

IRAS observations of the objects Sand. 3 and 209 BAC, the latter in the nebula M1-67, which were listed as WR72 and WR124 in the 6-th Catalogue of Galactic Population I Wolf-Rayet stars, show IR emission of circumstellar dust with respectively Tc ≈ 85K and Tc ≈ 100K. Such dust envelopes and the parameters the authors derive from them, are characteristic for planetary nebulae, confirming the planetary nucleus status of Sand. 3, [WO] and proving that of 209 BAC, [WN8].
