Session 57 - Astrophysical Diagnostics from Polarimetry.
Display session, Wednesday, June 12
The Wisconsin Ultraviolet Photo Polarimeter Experiment (WUPPE) flew twice as part of NASA's Astro Spacelab missions in 1990 December and 1995 March. A systematic survey of the interstellar polarization in the ultraviolet was one of the main projects for the flights. The program was designed to 1) sample the galactic plane as uniformly as practicable, 2) explore sight lines of diverse chemical composition and morphology and 3) measure the shape of the UV polarization through the full range of known wavelengths of peak polarization in the optical. We have also obtained new, high signal-to-noise and resolution optical polarization spectra of all the northern hemisphere objects observed by WUPPE with the University of Wisconsin's "HPOL" system on either the Pine Bluff Observatory 0.9-meter or the WIYN Observatory 3.5-meter telescopes. We present a compilation of these data, discuss preliminary conclusions and outline the plan for the analysis of this database.
