1996 is the year of the first extra-solar planet discoveries. 4 jupiter sized planets have been discovered so far around main sequence stars. we believe that the vega phenomenon (infrared excess emission due to dust disks around main sequence stars) is related to planet formation in that the left-over planetesimals are the likely source of the observed dust particles. of the four planetary systems, three are fortunately covered by iso observations looking for vega like excess. we propose to use 30 minutes of discretionary time to observe the newest example and, if possible, discover the disk associated with that star.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
