A Compilation of Optical Starlight Polarization Catalogs
The Astrophysical Journal Supplement SeriesPolarimetry of stars at optical and near-infrared wavelengths is an invaluable tool for tracing interstellar dust and magnetic fields. Recent studies have demonstrated the power of combining stellar polarimetry with distances from the Gaia mission, in ...

Probing 3D Magnetic Fields Using Starlight Polarization and Grain Alignment Theory
The Astrophysical JournalPolarization of starlight induced by dust grains aligned with the magnetic field (hereafter B -field) is widely used to measure the 2D B -fields projected onto the plane-of-sky.

Statistical Properties of Galactic Starlight Polarization [PDF]
Astrophysical Journal, 2002 We present a statistical analysis of Galactic interstellar polarization from the largest compilation available of starlight data. The data comprises ~ 9300 stars of which we have selected ~ 5500 for our analysis. We find a nearly linear growth of mean polarization degree with extinction.

Extreme starlight polarization in a region with highly polarized dust emission [PDF]
Astronomy and Astrophysics, 2019 Context. Galactic dust emission is polarized at unexpectedly high levels, as revealed by Planck. Aims. The origin of the observed ≃20% polarization fractions can be identified by characterizing the properties of optical starlight polarization in a region with maximally polarized dust emission. Methods.

Polarization Of Background Starlight And The Structure Of The Interstellar Magnetic Field [PDF]
Symposium - International Astronomical Union, 1991 We discuss the use of polarization maps of background starlight in studying the structure of the interstellar magnetic field. We make the assumption that the polarization observed is due to magnetically aligned dust grains associated with interstellar clouds along the line of sight, and that the position angle (Θ

The Guitar Filament’s Magnetic Field Revealed by Starlight Polarization
The Astrophysical JournalThe Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line of sight to the pulsar.

Demonstration of Magnetic Field Tomography with Starlight Polarization toward a Diffuse Sightline of the ISM [PDF]
Astrophysical Journal, 2019 Abstract The availability of large data sets with stellar distance and polarization information will enable a tomographic reconstruction of the (plane-of-the-sky-projected) interstellar magnetic field in the near future. We demonstrate the feasibility of such a decomposition within a small region of the diffuse interstellar medium (ISM).

Polarization of Starlight by an Unresolved and Oblate Extrasolar Planet in an Elliptical Orbit
Astrophysical Journal, 2006 We calculate the degree of linear polarization of radiation from stars having planets that may not be resolved spatially. We assume single scattering by water and silicate particulates in the planetary atmosphere. The dilution of the reflected polarized radiation of the planet by the unpolarized stellar radiation and the effect of oblateness of the ...
