Description The nearby young A-star beta Pictoris is well known for its large circumstellar dust disk. The disk is also known to contain gas, which from absorption lines in the UV is found to be overabundant in carbon by a factor ~20. Recently, Herschel/PACS observed very strong emission from the CII line which seems to indicate that the disk is even more abundant in carbon than previously thought, up to a factor of 100 above other elements. This is unexpected, and we propose to investigate this with HIFI high-resolution spectroscopy of the CII 157um line profile. From the known Keplerian velocity field and the line profile, we will be able to constrain the spatial location of the carbon and thus the total carbon mass. The spatial location of the carbon gas will also give clues to its origin, in particular if it is related to the recently discovered planet in a ~10 AU orbit around beta Pic.

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.
