Description | Beta Pictoris is a young (12 Myr) main-sequence star surrounded by at least one planet at a distance of virgul10 AU, and a dusty debris disk created by catastrophic collisions of planetesimals. We propose to make a deep observation of the 69 micron band of crystalline olivine in the debris disk of Beta Pictoris. The debris disk is resolved with HERSCHEL-PACS. This will enable us to study the collisional processes within the debris disk. The discovery of more than 600 exo-planets in the past two decades has shown an amazing diversity in the properties of planetary systems. The origin of this diversity and the way the solar system fits in must be understood by studying young systems in which planet formation is ongoing, and by comparing the properties of these young systems with the historic records of the formation of the solar system as recorded in e.g. asteroids and comets.Beta Pictoris is a unique object for this, since it is bright and it still shows spectral features since it is young enough to still have small grains. Previous studies have already shown that the crystalline olivine material in Beta Pictoris is very similar to that in our own Solar System. Using the integral-field-spectrometer PACS we will be able to look at the 69 micron band of crystalline olivine at the position where the material is created and further out in the disk. This enables us to follow the complete dust creation, avalanche and blow out processes in the disk. Understanding these collisional processes is very important since they strongly effect the properties, formation and evolution of planetary systems. |

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. |
