Wisconsin Ultraviolet Photo-Polarimeter Experiment

Published by MAST: Mikulski Archive at Space Telescope | National Aeronautics and Space Administration | Catalog Last Checked: July 14, 2026 at 11:02 PM | Dataset Last Updated: June 22, 2026
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was the spectropolarimetry component of the three ASTRO instruments that flew on Space Shuttle missions in December 1990 and March 1995. A halfwave spectropolarimeter provided medium resolution spectropolarimetry for research into the interstellar medium, hot stars, stars with circumstellar material, interacting binary stars, novae, solar system objects, and active galaxies. A Lyot analyzer obtained low resolution observations of faint targets, but due to calibration problems did not produce scientifically useful data. The WUPPE instrument provides a unique data set, one of the few providing polarimetric data in the ultraviolet portion of the spectrum.
