| Description | We propose to observe the circumstellar disks around 28 very low mass stars that lie between the sub-stellar limit at 0.08 msun and 0.3-0.5 msun, the level where disks are bright enough to be readily detectable in the large, shallow Herschel surveys. The objects are located in 4 different star-forming regions that span a range of ages from roughly 1 - 3 Myr. This sample will provide the data necessary to link our understanding of disk evolution around solar-mass stars to those around sub-stellar objects, already well-represented by Herschel GT1 and OT1 programs. We will use proven disk modeling codes developed by team members and used extensively for modeling disks around stars and brown dwarfs. This approach has already worked well in our GT1 program on sub-stellar objects and in our first publication about its initial results. |

| 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. |
