Talk abstract details

The Royal Observatory of Belgium is leading the Herschel Guaranteed Time Key Project “MESS” (Mass loss of Evolved StarS). This project has observed a wide variety of evolved stellar objects in spectroscopic and photometric mode using both the PACS and SPIRE instruments on board the Herschel satellite. The aims of the project are to study the mass loss history of the central star, the hydrodynamical interactions in the outflows and the properties of the dust that was formed in the ejecta. The project studies a wide variety of evolved objects, including planetary nebulae (PNe). In my talk I will give an overview of the most recent results that we obtained on PNe. This will include new imaging data of NGC 650 and NGC 6853, as well as recent spectroscopic results.
