Description ===================================================================== ===================================================================== this proposal is for a survey of a sample of 25 nearby f, g, and k main sequence stars for hot (terrestrial planet temperature) dust emission analogous to that from our zodiacal (zody) dust. this program is an extension of the ongoing iso rstencel.vegadis5,6,7,8 programs that consist of a survey of a-m main sequence stars for cold dust emission as in the vega / beta pic systems. zody dust is planetary material, mostly produced by asteroid collisions. detection of zody dust around a solar-type star would be a good indicator of planets orbiting in roughly the same temperature regime. several nearby stellar systems have been found in the last year to have perturbing bodies with masses of order that of jupiter. jupiters apparently may be found orbiting solar-type stars at radii anywhere from 0.05 to 5+ au. in collaboration with geoff marcy we propose here to examine a subset of his radial velocity planet-search stars for for evidence of zody dust. our subset contains 6 stars with and 19 stars without detected planetary pertubations. this investigation will use the isopht 16 and 20 micron filters. these are chosen to span the wavelength range around the blackbody peak of terrestrial planet material where the combination of contrast to a stellar photosphere and sensitivity of iso photometry is most favorable. photometry at 16 microns is impossible from the ground and can be done at 20 microns with the necessary precision only with great difficulty at the largest telescopes.

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.
