We propose Herschel PACS and SPIRE imaging of asample of 26 Classical Cepheids, to map their far-IRcircumstellar emission. All targets have been previouslyimaged with Spitzer/IRAC and MIPS. Herschel data willallow to characterize the nature of the nebulosity for allsources, and differentiate it from Galactic Cirrusbackground emission and local ISM clouds. This willprovide an accurate and unbiased estimate of Cepheidmass loss rates, crucial for resolving the Cepheids massdiscrepancy.

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.
