| Description | from our survey of vega type stars we found that the g2v star hd207129 exhibits an infrared excess suggesting a very cold disk of 25-65 k. this is likely the coldest excess detected so far. unfortunately, the present infrared observations are not sufficient to constrain the disk parameters more accurately. we propose iso follow-up observations to determine the full infrared properties of hd207129 which has a spectral type closely resembling our sun. photometric and spectrophotometric observations with pht and cam-cvf are requested to determine the onset point of the excess. the cam cvf scanning is also used to detect possible silicate emission from the disk. based on the outcome of these observations we request to perform dedicated coronographic observations with cam in the process testing a special observing mode. to determine the extent of the disk at 60 micron we would like to apply high resolution scanning with pht, which has become available recently. |

| 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. |
