| Description | We propose to obtain Herchel PACS imaging and spectroscopy of G54.1+0.3, a young pulsar wind nebula (PWN) surrounded by a shell of supernova (SN) ejecta and freshly-formed dust. The dust and gas seem to be illuminated by the expanding PWN and the members of a stellar cluster in which the SN exploded, making them observable at infrared wavelengths. Our recent Spitzer study suggests that the shell contains 0.1 solar masses of dust, possibly the largest amount observed to date, and that this dust has not yet been processed by supernova remnant (SNR) shocks. The proposed observations will allow us to 1) determine the composition, temperature, mass, and spatial distribution of pristine SN dust that has not been altered by shocks, 2) search for a colder dust component to constrain the total amount of dust in the system, and 3) measure composition and velocity of the surrounding SN ejecta that will provide information on the SN progenitor and the evolution of the PWN. A Hersche study of this unique system promises to shed light on the outstanding questions regarding the nature and quantity of dust produced in SNe. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
