Herschel: le bilan en planétologie (système solaire et disques de débris)


The Herschel space observatory was launch in may 2009 and ended its mission on 29 april 2013. Its three instruments, HIF, SPIRE and PACS covered the 55-670µm wavelength range, particularly well suited to study the rotational lines of water and the thermal emission of cool bodies. It has enabled several unprecedented discoveries in the field of the physical study of debris disks, thermal and physical properties of the small bodies of the solar system, the composition of cometary and planetary atmospheres,... The goal of this workshop is to show the extent of the results obtained with Herschel in the planetology domain (from debris disks to the solar system). A brief overview of the modeling of the evolution of planetary systems will also be given to put Herschel results in the context of our understanding of the evolution of our solar system and stelar systems in general.
