The star Cnc is among the first 10 stars which have been shown to host a planet. Following the discovery of the planet in 1996 we have obtained ISO observations in May 1996. The observations show that Cnc has a 25µm flux consistent (within the errors) with photospheric origin, and an excess of 170 30 mJy at 60µm. We interprete this excess as emission from dust grains in a Vega-like disk located approximately 60 AU from the star, containing at least of material.
Key words: stars: planetary systems stars: general stars: individual: ae1 Cnc Infrared: stars
* Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, The Netherlands and the United Kingdom) and with the participation of ISAS and NASA.
