This proposal on "The Magnetic Structure of Stellar Atmospheres"                between Drs. Jeffrey L. Linsky, James E. Neff, and Steven H. Saar               of the University of Colorado at Boulder and Dr. Ilkka Vilhelmi                 Tuominen of the University of Helsinki, is jointly approved by NSF              and the Academy of Finland under the U.S.-Finland Cooperative                   Science Program.                                                                                                                                                The emission from outer atmospheres of late-type stars arises not               homogeneously (as most current models assume), but from discrete,               magnetically confined regions.  Attempts to probe this structure                on the most active, most rapidly-rotating start with spectral                   ("Doppler") imaging techniques yield a picture of the magnetic                  field morphology but no information about the field strength.                   Measurements of field strengths on slowly rotating, relatively                  inactive stars, provide the mean field strength but no information              about the field morphology.  However, simultaneous measurements of              broad-band linear polarization (BLP) can help interpret the                     results of each program, as BLP provides some magnetic flux                     information for rapid rotators and some field morphology information            for slow rotators.                                                                                                                                              The researchers propose to exploit the potential of BLP observations            by bringing together the unique magnetic field and spectral                     imaging data sets of the University of Colorado at Boulder with                 the best available BLP data, that of the University of Helsinki                 Observatory.  The American researchers will obtain new observations             using the University of Helsinki photopolarimeters and high-                    resolution spectrographs at the Crimean Astrophysical Observatory               and at the Nordic Optical Telescope with their other observing                  programs.
