Abstract

We searched the Spitzer Space Telescope data archive for Galactic planetary nebulae (PNe), which show the characteristic 17.4 and 18.9 μm features due to C 60, also known as buckminsterfullerene. Out of 338 objects with Spitzer/Infrared Spectrograph data, we found eleven C 60-containing PNe, six of which (Hen2-68, IC2501, K3-62, M1-6, M1-9 and SaSt2-3) are new detections, not known to contain C 60 prior to this work. The strongest 17.4 and 18.9 μm C 60 features are seen in Tc1 and SaSt2-3, and these two sources also ...
