A Vega--like disk associated with the planetary system of rho (1) CNC

The star {rho (1) 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 {rho (1) Cnc} has a 25mu m flux consistent (within the errors) with photospheric origin, and an excess of 170+/-30 mJy at 60mu m. We interprete this excess as emission from dust grains in a {Vega}-like disk located approximately 60 AU from the star, containing at least 4*E(-5) M_⊕ of material. 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.
