Description We propose to map emission from cold (<30 K), newly-formed dust in the ejecta of the core-collapse supernova remnant 1E 0102.2-7219 (E 0102) using Herschel PACS observations. E 0102 is a key object for understanding supernova dust production: it is one of few remnants where we have clear evidence of dust formation from mid-IR observations of ~10^-3 solar masses of hot dust in the reverse shocked ejecta. A large fraction of the newly-formed dust, however, may be located in the central, unshocked ejecta and its cold temperatures have kept it hidden at mid-IR wavelengths thus far. Observations with PACS at 70, 100 and 160 microns have the sensitivity and angular resolution to measure the mass of dust in the unshocked ejecta of E 0102 for the first time. With the observations proposed here, we will either discover a reservoir of cold dust in E 0102 or provide a direct counter-example to recent theoretical and observational studies that suggest supernovae are important sources of ISM dust.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
