Infrared space observatory photometry of circumstellar dust in Vega-type systems

The ISOPHOT (Infrared Space Observatory Photometry) instrument onboard the Infrared Space Observatory (ISO) was used to obtain 3.6-90 micron photometry of Vega-type systems. Photometric data were calibrated with the ISOPHOT fine calibration source 1 (FCS1). Linear regression was used to derive transformations to make comparisons to ground-based and IRAS photometry systems possible. These transformations were applied to the photometry of 14 main-sequence stars. Details of these results are reported on.

A Precision Pointing Control System for The Space Infrared Telescope Facility (SIRTF)

The SIRTF telescope carries on-board imaging, spectroscopy, and photometry instrumentation to investigate fundamental questions about the early universe, formation and evolution of galaxies, and formation of planetary systems, based on infrared astronomical observations.
