Description |
We propose Herschel PACS and SPIRE imaging of a sample of 26 Classical Cepheids, to map their far-IR circumstellar emission. All targets have been previously imaged with Spitzer-IRAC and MIPS. Herschel data will allow to characterize the nature of the nebulosity for all sources, and differentiate it from Galactic Cirrus. background emission and local ISM clouds. This will provide an accurate and unbiased estimate of Cepheid mass loss rates, crucial for resolving the Cepheids mass discrepancy.. |
