    Polarimetric Measurements of Sunspots
    Making emphasis on observations that have included some type of polarization analysis, I concentrate on two subjects. First, the vector magnetic field...

    Polarimetry toward the IRAS Vela Shell. I. The Catalog
    We have obtained linear polarization measurements of stars along the western side of the IRAS Vela Shell toward HD 62542. From 16 CCD fields distributed along...

    Polarimetry toward the IRAS Vela Shell. II. Extinction and Magnetic Fields
    We explore correlations between visual extinction and polarization along the western side of the Infrared Astronomical Satellite (IRAS) Vela Shell using a...

    Polarimetry toward the Musca Dark Cloud. I. The Catalog
    We have used CCD imaging polarimetry to obtain linear polarization measurements of background stars toward the filamentary Musca dark cloud. We present a...

    Polarisation and magnetic fields in cool stars and the Sun. A session in memory of Meir Semel
    Astrophysical plasmas and magnetic fields are inextricably coupled to each other. But magnetic fields are elusive; they cannot be fully characterized with...

    Polarization : Proving ground for methods in radiative transfer.
    Polarization of solar lines arises due to illumination of radiating atom by anisotropic (limb darkened/brightened) radiation. Modelling the polarized spectra of...

    Polarization Accuracy Verification of the Chromospheric LAyer SpectroPolarimeter
    We have developed an advanced UV spectropolarimeter called Chromospheric LAyer SpectroPolarimeter (CLASP2), aimed at achieving very high accuracy measurements (...

    Polarization of Photospheric Lines from Turbulent Dynamo Simulations
    We employ the magnetic and velocity fields from turbulent dynamo simulations to synthesize the polarization of a typical photospheric line. The synthetic Stokes...

    Polynomial Approximants for the Calculation of Polarization Profiles in the He I 10830 Å Multiplet
    The He I multiplet at 10830 Å is formed in the incomplete Paschen-Back regime for typical conditions found in solar and stellar atmospheres. The positions and...
